Least Common Multiple (LCM) calculator - finds LCM for up to three given numbers and shows process of dividing by primes as for school-like interpretation.

Some facts

**Least common multiple**is the smallest positive integer that is a multiple of two or more numbers. This means also, it can be divided by these numbers without a reminder.**Least common multiple (LCM)**is sometimes called**lowest common multiple**or**smallest common multiple****LCM**is mainly useful as**lowest common denominator**for fractions.

How to use this tool

To search for **greatest common divisor** or **least common multiplier** enter your numbers into fields below.

You can enter 2 or 3 integer numbers. If you need only 2 of them - just leave 3rd field empty!

All numbers should be non-zero integer (so you can use negative numbers).
