#### What is the LCM of GCF?

The difference between GCF and LCM is self explanatory. While GCF is the largest number shared between the factors of two or more numbers, LCM is the smallest number that is divisible by both (or more) the numbers. To find either the LCM or the GCF of 2 or more numbers, it is necessary to factorize them.
