Why do you multiply the prime numbers together to find the LCM?

You multiply numbers because you're trying to find a multiple. You multiply prime numbers because you're trying to find the smallest common number. You could multiply common composite factors, but the result wouldn't necessarily be least.

Least common multiple for 7 and 17?
7 and 17 are both primes numbers. The means that to find the LCM we need multiply them. The LCM of 7 and 17 is 7x17 which is 119. If two numbers are prime, then they are also relatively prime and in general the way to find the LCM of relatively prime number is to multiply them together.
What is the prime factorization of 2x2x7x7?
Prime factorization is a list of all the primes that multiply to make the original number. Thus to find that number you just multiply all these numbers together. In this case we have 2, 2, 7 and 7, so multiply them together to get: 2x2x7x7 = 296. Therefore, 2x2x7x7 is the prime factorization of 296.
