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).
Practice along with the Academy. Enjoy
