Definition of least common multiple. 1 : the smallest common multiple of two or more numbers. 2 : the common multiple of lowest degree of two or more polynomials.

## How is GCF used with fractions?

GCF is a fraction smaller than both the fractions or equal to one or both of them (when both fractions are equal). When you take the GCF of the numerator and LCM of the denominator, you are making a fraction smaller than (or equal to) the numbers.

## How do you explain Greatest Common Factor?

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor. Example: the GCF of 12 and 16 is 4, because 1, 2 and 4 are common factors of both 12 and 16, and 4 is the greatest of them.
