The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.

The least common multiple of 40 and 60 is 120.

Factor them.

2 x 2 x 2 x 5 = 40

2 x 2 x 3 x 5 = 60

Select the highest amount of each factor.

2 x 2 x 2 x 3 x 5 = 120, the LCM
