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.
- 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).
If you need only 2 numbers - just leave 3rd field empty!
