# Lowest Common Multiple

The **Lowest Common Multiple (LCM)** is the smallest number into which two given numbers will divide.

To find the LCM, list the **multiples** of each given number until you see one multiple common to both numbers.

## Examples

**NUMBERS** | **MULTIPLES** | **LOWEST COMMON MULTIPLE** |

4 | 4, 8, **12**, 16, 20, 24 | The LCM is **12**. |

6 | 6, **12**, 18, 24 |

**NUMBERS** | **MULTIPLES** | **LOWEST COMMON MULTIPLE** |

5 | 5, 10, 15, 20, 25, 30, 35, **40** | The LCM is **40**. |

8 | 8, 16, 24, 32, **40** |
