LCM & GCD Calculator
Calculate the Least Common Multiple (LCM) and Greatest Common Divisor (GCD) of two or more numbers using the Euclidean algorithm.
How to Use LCM & GCD Calculator
The LCM & GCD Calculator computes both the Least Common Multiple and Greatest Common Divisor for two or more numbers simultaneously. Enter your numbers separated by commas or spaces and get instant results using the Euclidean algorithm. The GCD (also called HCF) is the largest number that divides all inputs evenly, while the LCM is the smallest number that all inputs divide into evenly. Essential for simplifying fractions, finding common denominators, solving number theory problems, and scheduling calculations. Works with any set of non-zero integers.
