LCM Calculator

The LCM Calculator is a quick and reliable online tool that helps you find the Least Common Multiple (LCM) of two or more numbers in seconds. Whether you're a student solving math problems, a teacher preparing lessons, or just someone working with fractions or time intervals, this tool makes calculating the LCM effortless and error-free.

🔢 What is LCM (Least Common Multiple)?

The Least Common Multiple of two or more numbers is the smallest number that is a multiple of all the given numbers. In other words, it's the smallest positive number that all the input numbers divide evenly into.

📐 LCM Formula

There are multiple ways to find the LCM, but a common and efficient method uses the relationship between LCM and GCD (Greatest Common Divisor):

LCM(a, b) = |a × b| / GCD(a, b)

This formula works well for finding the LCM of two numbers. For more than two numbers, pairwise LCMs are calculated sequentially.

✍️ Example Calculation:

Let's find the LCM of 6 and 8:

Multiples of 6: 6, 12, 18, 24, 30, ...

Multiples of 8: 8, 16, 24, 32, 40, ...

The lowest common multiple is 24.

✅ So, LCM(6, 8) = 24
