One of my “ah ha” moments this week was in Lesson #2.

When we were first looking at the differences between the greatest common factor, (GCF) and the least common multiple, (LCF) I wasn’t sure how to find each of these.

When I knew that we could use prime factorization to determine both of them, I tried the first question out when we were taking notes:

I soon realized when told that we could easily figure out the GCF & LCM from prime factorization by:

-taking the smallest exponents to find the GCF

-taking the largest exponents to find the LCM

By multiplying the smallest/largest exponents from the factorization, it gives you the answer. This tool made it much faster for me to find the exact answer I was looking for, rather than guessing.
