GCF & LCM

Least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers.

Greatest common factor (GCF) of two numbers is the largest number that is a factor of both numbers.

To find either the Least Common Multiple (LCM) or Greatest Common Factor (GCF) of two numbers, you always start out the same way: you find the prime factorizations of the two numbers. Then you put the factors into a nice neat grid of rows and columns, and compare and contrast and take what you need.
