The main purpose of creating this article is to boost confidence in solving any type of question in an efficient manner. In this article, let us learn how to derive the least common multiple of 6, 8 and 12 in detail.

## What is LCM of 6, 8 and 12?

The answer to this question is 24.

## How to Find LCM of 6, 8 and 12?

The LCM of 6, 8 and 12 can be determined using three methods:

- Prime Factorisation
- Division method
- Listing the multiples

### LCM of 6, 8 and 12 Using Prime Factorisation Method

In the prime factorisation method, we can express the numbers as the product of prime numbers. Therefore, the numbers 6, 8 and 12 can be expressed as;

6 = 2 × 3

8 = 2 × 2 × 2

12 = 2 × 2 × 3

LCM (6, 8, 12) = 2 × 2 × 2 × 3 = 24

### LCM of 6, 8 and 12 Using Division Method

In the division method, we divide the numbers 6, 8 and 12 by their prime factors until we get the result as one in the complete row to calculate their LCM. The product of these divisors represents the least common multiple of 6, 8 and 12.

2 | 6 | 8 | 12 |

2 | 3 | 4 | 6 |

2 | 3 | 2 | 3 |

3 | 3 | 1 | 3 |

x | 1 | 1 | 1 |

No more further division can be done.

Hence, LCM (6, 8, 12) = 2 × 2 × 2 × 3 = 24
