Least common multiple (LCM) calculator. LCM is also known as least common denominator (LCD).
For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30. The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.
Find the least common multiple number for numbers 8 and 12:
The multiples of 8 are:
8, 16, 24, 32, 40, ...
The multiples of 12 are:
12, 24, 36, 48, ...
So the least common multiple number is 24:
lcm = 24
