Least Common Multiple (LCM) Calculator
Frequently Asked Questions
What is the Least Common Multiple (LCM)?
The Least Common Multiple (LCM) is the smallest positive number that is divisible by two or more numbers.
How is LCM calculated?
LCM can be calculated by prime factorization or by using the formula: LCM(a,b) = |a × b| ÷ GCD(a,b)
Why is LCM important?
LCM is useful in many mathematical applications, including fraction operations and solving real-world problems involving cycles or patterns.
Understanding Least Common Multiple
The Least Common Multiple (LCM) is a fundamental concept in mathematics that helps us find the smallest number that is divisible by two or more numbers. This calculator provides a quick and accurate way to find the LCM of any two positive integers.
Common LCM Examples
