The tool will display the GCD (MDC) and LCM (MMC) for the entire set.

Frequently Asked Questions

What is GCD (MDC)?

The Greatest Common Divisor is the largest positive integer that divides each of the integers without a remainder.

What is LCM (MMC)?

The Least Common Multiple is the smallest positive integer that is divisible by all the numbers in the set.

How are they related?

For two numbers a and b, the relationship is: LCM(a, b) = |a * b| / GCD(a, b).
