Problem: Article: This method works best when both of the numbers you are working with are greater than 10. If you have smaller numbers, you can use a different method to find the least common multiple more quickly. For example, if you need to find the least common multiple of 20 and 84, you should use this method. You want to factor the number into its prime factors; that is, find the prime factors you can multiply together to get this number. One way to do this is by creating a factor tree. Once you are done factoring, rewrite the prime factors as an equation. For example, 210=20{\displaystyle \mathbf {2} imes 10=20} and 25=10{\displaystyle \mathbf {2} imes \mathbf {5} =10}, so the prime factors of 20 are 2, 2, and 5. Rewriting as an equation, you get 20=225{\displaystyle 20=2 imes 2 imes 5}. Do this in the same way you factored the first number, finding the prime factors you can multiply together to get the number. For example, 242=84{\displaystyle \mathbf {2} imes 42=84}, 76=42{\displaystyle \mathbf {7} imes 6=42}, and 32=6{\displaystyle \mathbf {3} imes \mathbf {2} =6}, so the prime factors of 84 are 2, 7, 3, and 2. Rewriting as an equation, you get 84=2732{\displaystyle 84=2 imes 7 imes 3 imes 2}. Write the factors as a multiplication sentence. As you write each factor, cross it off in each numbers factorization equation. For example, both numbers share a factor of 2, so write 2{\displaystyle 2 imes } and cross out a 2 in each number's factorization equation. Each number also shares a second 2, so change the multiplication sentence to 22{\displaystyle 2 imes 2} and cross out a second 2 in each factorization equation. These are the factors you did not cross out when comparing the two groups of factors. Thus, these are factors that the two numbers do not share. For example, in the equation 20=225{\displaystyle 20=2 imes 2 imes 5}, you crossed out both 2s, since these factors were shared with the other number. You have a factor of 5 left over, so add this to your multiplication sentence: 225{\displaystyle 2 imes 2 imes 5}. In the equation 84=2732{\displaystyle 84=2 imes 7 imes 3 imes 2}, you also crossed out both 2s. You have the factors 7 and 3 left over, so add these to your multiplication sentence: 22573{\displaystyle 2 imes 2 imes 5 imes 7 imes 3}. To do this, multiply together all of the factors in your multiplication sentence. For example, 22573=420{\displaystyle 2 imes 2 imes 5 imes 7 imes 3=420}. So, the least common multiple of 20 and 84 is 420.
Summary: Assess your numbers. Factor the first number. Factor the second number. Write down the factors each number shares. Add any leftover factors to the multiplication sentence. Calculate the least common multiple.

Problem: Article: Muggers and other violent criminals try to prey on easy targets: people who aren't very aware of their environment and who can be ambushed easily. So, instead of walking with your head pointed down looking at your phone, stand up straight, walk briskly, and keep your shoulders back and chin up. Avoid making eye contact with anyone who you feel may be following you, but do glance around yourself so you're aware of your surroundings. If a would-be attacker feels that you'd make a difficult target, they'll leave you alone. If the potential aggressor starts to speak to you roughly, say calming things to diffuse the situation. Ideally, you'll calm the aggressor down, or at least buy yourself enough time to leave the scene. Try saying something like, "Look, I don't think there's any reason for you to be aggressive. I'm going to get in my car and drive away now. Don't follow me." Even if the aggressor raises their voice or says insulting things, don't get into a shouting match. Stay calm and try to diffuse the situation so you can leave. When someone is approaching you aggressively, try to get away by ducking into your vehicle, walking inside a business, or blending into a crowd. If you have a chance to flee and escape a potential attack without fighting, do it. Try throwing a wallet or watch in 1 direction and then run in the opposite direction to escape. Or, if an attacker asks for your wallet, credit cards, jacket, or shoes, hand the items over. It's not worth potentially losing your life just to hang on to some money. In nearly all cases, attackers look for victims who they can easilyand quietlysubdue. Most will avoid loud situations that could draw other people (or even the police) to the scene. So, if someone is approaching you and may attack, loudly shout "Back off!" If they advance further, keep shouting. Yell something like, "Get out of here!" or "Leave me alone!" If you have a cell phone with you, you could pull it out and shout, "I'm calling 911 right now if you don't back off!" in case the aggressor attacks you. If you can't escape or diffuse the situation, begin preparing yourself for a strike. Stand with your feet shoulder-width apart with your non-dominate leg in front and pointing outward. Keep your weight centered over both feet. Crouch a little so that your center of gravity is low, and bring up your hands to protect your face. This stance will make it harder to fight you and will give you more control when you need to defend yourself. Keeping your body compact will prevent you from flailing and will make it easier to keep your balance during strikes.
Summary: Project confidence and awareness so that you're not an easy target. Talk your way out of a fight to avoid physical violence. Escape the scene to lose the attacker if you have the opportunity. Shout at the aggressor to deter them from attacking you. Stand in a defensive position

Problem: Article: Schedule a visit with your doctor to discuss the benefits and detriments of using this product. Discuss the effect DMSO may have on other supplements or medications you are taking, as it may increase the effectiveness of certain medications, including blood thinners, sedatives, and steroids. Ask your doctor for concentration and dosage recommendations as well. Be sure to let your doctor know of any other medical conditions you have, including diabetes, asthma, and liver or kidney problems, as DMSO may worsen these conditions. Side effects of DMSO may include an odor of garlic, skin irritation, and upset stomach. More serious reactions include itching or burning at the application site, headache, and severe allergic reactions. If you have an adverse reaction, stop using DMSO and contact your doctor. In the case of a severe allergic reaction, obtain emergency medical attention. Taking DMSO orally can cause dizziness, nausea, vomiting, diarrhea, constipation, drowsiness, and decreased appetite. Until the safety of taking DMSO by mouth or through injection has been established, only apply it topically or through a catheter with your doctor's approval and under their supervision.
Summary:
Consult your doctor before you begin using DMSO. Look for adverse reactions. Avoid taking DMSO by mouth or through injection.
