Lowest Common Multiple and Greatest Common Factor

Here is a video to help out with our discussions on LCM and GCF.

Greatest Common Factor

Greatest common factor exercise: Find the biggest number that will divide into the given 2 numbers. This is called the GCF or greatest common factor.No worries, we'll show you how to do it.


Least Common Multiple

Least common multiple exercise: We're practicing finding the least common multiple in these example exercises. We'll teach you the prime factorization approach which is a pretty nifty way to find the lcm (least common multiple).
