Least common multiple of numbers.
The LCM Calculator finds the least common multiple of a list of whole numbers — the smallest positive number that every value divides into evenly. It handles two or more numbers at once and also shows their greatest common factor.
The LCM is essential for adding or comparing fractions, scheduling repeating events, and any problem where cycles need to line up.
For more than two numbers, the LCM is built up pairwise: lcm(a, b, c) = lcm(lcm(a, b), c).
The smallest positive whole number that each of your numbers divides into with no remainder.
To add or subtract fractions you convert them to a common denominator, which is the LCM of the original denominators.
Multiples are defined for integers. Decimals have no meaningful least common multiple.
If two numbers share no common factor other than 1, their LCM is just their product.
