Just like GCF's, we can use prime factorizations to find LCM's. As before, this one is probably at the pre-algebra level.
The Prime Factorization Method:
Let's work with numbers that we've already crunched the prime factorizations for...
|List the prime factorization of each using exponents:
|Take the larger of each of the exponents...
|Multiply these together to get the answer:
Check this using multiple lists!
