LCM Calculator: Tool for
Finding Least Common Multiple

This free online least common multiple tool will find the LCM of 2, 3, or 4 numbers at once with the click of a button.
Plus, in addition to displaying the LCM, the calculator will also display all preceding multiples for each number, along with the number of times each number divides into the LCM.

What Are Multiples?

The multiples of a number is the set of all numbers that it can be multiplied into evenly. For example, the multiples of the number 2 would be as follows:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, ...

What is a Common Multiple?

A common multiple occurs when two or more numbers share one or more of the same multiples. For example, the numbers 2 and 8 have the following common multiples because both can divided evenly into each number listed:

Common Multiples of 2 & 8: 8, 16, 24, 32, 40, 48, 56, ...

What is a Least Common Multiple?

A least common multiple (LCM) is the lowest multiple that two or more numbers share. Referring back to the numbers 2 and 8, the LCM would be 8 based on the following set of multiples:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, ...
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, ...

With that, let's use the LCM Calculator to find the least common multiple of up to 4 different numbers.
