## Elementary Math (K-6th) Tutorial

*Least Common Multiple *

#### Intro

Find the LCM of 6 and 4 using prime factorization.

Let’s find multiples of these two numbers.

6:6,12,18,24,30,….

4:4,8,12,32,40,….

#### Sample Problem

#### Solution

Find the first few multiples of the two numbers as follows:

6: 6 , 12 , 18 , 24 , 30 ,…

4: 4 , 8 , 12 , 32 , 40 ,…

The lowest multiple that is common to 6 and 4 is 12. So the LCM of 6 and 4 is 12.

The above method works well for small numbers only.
