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

## 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.
