The greatest common factor, or GCF, is the largest number that will divide into all the members of a given set of numbers evenly. The least common multiple, or LCM, is the smallest number that all the members of a given set will divide into evenly.
Example: 30 and 42
The GCF is 6.
The LCM is 210.

What is the least common multiple of 64 and 56?
The least common multiple is the product of the two numbers divided by their greatest common factor. Their greatest common factor is 8, so the least common multiple is 56 x 64 ÷ 8 = 448.
What is the greatest common factor and least common multiple of 15?
Itself
What is the least common multiple of 44 and 60?
The least common multiple is the product of the two numbers divided by their greatest common factor. The greatest common factor of 44 and 60 is 4, so the least common multiple is 44 x 60 ÷ 4 = 660.
How do you know whether to use the greatest common factor or the least common multiple to solve a problem?
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
What is the greatest common multiple of 15 and 45 and the least common multiple of 15 and 45?
The Greatest Common Factor of 15, 45: 15The Least Common Multiple of 15, 45: 45
What is the least common multiple of 5 and 23?
The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 5 and 23 is 1. (See related question "What is the greatest common factor of 5 and 23?" for this calculation.) So, the least common multiple is 5 x 23 ÷ 1 = 115.
