LCM Calculator
Calculate the Least Common Multiple (LCM) of two or more numbers instantly.
LCM Calculator
Enter numbers separated by commas to find their LCM.
Formula Used:
LCM(a, b) = (a × b) / GCD(a, b)
For multiple numbers, find LCM of first two, then with next number, and so on.
Common Examples
What is the Least Common Multiple (LCM)?
The Least Common Multiple (LCM) of two or more numbers is the smallest positive integer that is divisible by each of the given numbers without leaving a remainder. It is a fundamental concept in mathematics with applications in fractions, scheduling, and problem solving.
The calculator uses the relationship between LCM and GCD (Greatest Common Divisor) to provide accurate results for any set of numbers.

Frequently Asked Questions
What is the Least Common Multiple (LCM)?
The LCM of two or more numbers is the smallest positive integer that is divisible by each of the given numbers without leaving a remainder.
How do you calculate LCM?
For two numbers, LCM = (a × b) / GCD(a, b). For multiple numbers, find the LCM of the first two, then find the LCM of that result with the next number, and so on.
Can I calculate LCM for more than two numbers?
Yes! This calculator supports multiple numbers. Enter them separated by commas (e.g., 12, 18, 24).
What is the difference between LCM and GCD?
LCM (Least Common Multiple) is the smallest number that is a multiple of all given numbers, while GCD (Greatest Common Divisor) is the largest number that divides all given numbers evenly.
