Question: what is the least common multiple of 8 and 14 using prime factorization?
Answer: Alternatively, the lcm of 8 and 14 can be found using the prime factorization of 8 and 14: The prime factorization of 8 is: 2 x 2 x 2. The prime factorization of 14 is: 2 x 7. Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(8,8) = 56.
