## How do you find the LCM in math?

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 explain LCM?

The Least Common Multiple ( LCM ) of a group of numbers is the smallest number that is a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that is both a multiple of 16 and a multiple of 20. You can find the LCM of two or more numbers through various methods.

## What is the LCM of 4 and 5?

In our previous example, the smallest of the common multiples is 20 so the Least Common Multiple of 4 and 5 is 20.
