user: I've been shopping around on Amazon and stumbled upon a product with the ASIN 'B075H2B962'. I'm curious about what it actually is, so could you help me find out the product name?

On a different note, I'm brushing up on my math skills, and currently, I'm trying to figure out the number of different ways I can arrange 4 out of 10 unique items. Can you calculate that for me?

Also, I'm helping my nephew with his math homework, and we're stuck on finding the greatest common divisor of 36 and 48. Could you work that out?

Lastly, I'm in the process of buying a new home and considering a mortgage. I need to budget my finances, so for a loan amount of $200,000 with a 5% interest rate over 30 years, what would my monthly payment be?
