GCD & LCM Calculator
Greatest common divisor and least common multiple of any numbers. Find the GCD (HCF) and LCM of two or more numbers instantly. Step-count shown via the Euclidean algorithm. Free online GCD and LCM calculator.
Tentang GCD & LCM Calculator
The greatest common divisor (or highest common factor) is the largest number dividing all your inputs exactly; the least common multiple is the smallest number they all divide into. These two values power fraction simplification, gear-ratio problems and scheduling cycles — "when do two blinking lights sync?". Enter two or more integers and this calculator returns both results with the count of Euclidean algorithm steps used to find them.
