Question

What is the least common multiple {LCM} and the greatest common factor {GCF} of 9 and 12?

Answer 1

The LCM (least common multiple) of 9 and 12 is 36 and the GCF (greatest common factor) is 3

Answer 2

Answer:

The LCM of 9 and 12 is 36. The GCF is 3

Step-by-step explanation:

To get the Least Common Multiple (LCM) of 9 and 12 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:  2 x 2 x 3 x 3 = 36

To get the Greatest Common Factor (GCF) of 9 and 12 we need to factor each value, that should give you 3.
