If it's not what You are looking for type in the calculator fields your own values, and You will get the solution.

To find the least common multiple of two numbers just type them in and get the solution.

To get the Least Common Multiple (LCM) of 15 and 21 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:

15: | 3 | 5 | |

21: | 3 | 7 | |

LCM: | 3 | 5 | 7 |

**The Least Common Multiple (LCM) is: 3 x 5 x 7 = 105**
