## About Least Common Multiple Calculator

The Least Common Multiple Calculator is used to find out the least common multiple (LCM) of two or more positive integers (proved by prime factorization calculation).

## Least Common Multiple

The least common multiple (also called the lowest common multiple or smallest common multiple) of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is a multiple of both a and b. The least common multiple of more than two integers or rational numbers is well-defined: it is the smallest number that is an integer multiple of each of them.
