## How do you calculate least common multiple?

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

## How do you find the least common multiple?

Calculate the least common multiple. To do this, multiply together all of the factors in your multiplication sentence. For example, 2×2×5×7×3=420{\\displaystyle 2\imes 2\imes 5\imes 7\imes 3=420}. So, the least common multiple of 20 and 84 is 420.
