12, 18, 24input numbers
Find the Least Common Multiple (LCM) for any set of 2 or more integers.
Formula & Method
- LCM Formula:
LCM(a, b) = (|a × b|) ÷ GCD(a, b) - For 3+ Numbers:
LCM(a, b, c) = LCM(LCM(a, b), c)
Worked Example
For numbers 12, 18, 24:
LCM(12, 18) = 36LCM(36, 24) = 72
Frequently Asked Questions
What is the Least Common Multiple (LCM)?+
The Least Common Multiple (LCM), also called Lowest Common Multiple, is the smallest positive integer that is divisible by all numbers in a given set without leaving a remainder.
How is LCM calculated from GCD?+
For two numbers a and b, LCM(a, b) = (|a × b|) / GCD(a, b).
Can I calculate the LCM of 3 or more numbers?+
Yes. Enter multiple numbers separated by commas or spaces to compute their combined LCM.
