What are GCD and LCM?

The Greatest Common Divisor (GCD) — also called Greatest Common Factor (GCF) or Highest Common Factor (HCF) — is the largest positive integer that divides all given numbers without a remainder. Example: GCD(12, 18) = 6, because 6 is the largest number that divides both. The Least Common Multiple (LCM) is the smallest positive integer that is divisible by all given numbers. Example: LCM(4, 6) = 12. These two values are mathematically related by the identity: GCD(a,b) × LCM(a,b) = a × b. Our calculator uses the Euclidean algorithm — one of the oldest algorithms in existence, dating to ~300 BCE — and shows every step so you can follow the process.

Real-world uses of GCD and LCM

GCD is used to simplify fractions to their lowest terms (e.g., 12/18 → divide both by GCD(12,18)=6 → 2/3). LCM is used whenever you need to find a common cycle: bus schedules synchronising at the same stop, medication doses given at different intervals that coincide, gear ratios in mechanical systems, and recurring payment cycles in finance. If two events repeat every 4 and 6 days respectively, LCM(4,6) = 12 tells you they next coincide in 12 days. Combine with our Prime Number Checker for deep number theory exploration.
