How to Find the Least Common Multiple without LCM Calculator?

There are other ways to calculate the LCM without the LCM calculator, but you can try the method below:

1. List the multiples of each number then look for the smallest number that appears in every list.
Example: Find the least common multiple for 2, 3, and 4.

List the multiples of 2, 3 and 4:
Multiples of 2 are 4, 6, 8, 10, 12, 14, 16...
Multiples of 3 are 6, 9, 12, 15, 18, 21, 24...
Multiples of 4 are 8, 12, 16, 20, 94...
2. Now, when you look at the list of multiples, you can see that 12 is the smallest number that appears in each list.
3. Consequently, the least common multiple of 2, 3 and 4 is 12.
