Calculate the Greatest Common Divisor (GCD/GCF) using Euclidean algorithm and prime factors.
Find the Greatest Common Divisor (GCD) or Greatest Common Factor (GCF) of two or more numbers. Displays step-by-step Euclidean algorithm divisions, divisor lists, and prime factorization overlaps.
Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our GCD Calculator operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.

Common Divisors: 1, 2, 3, 6
Are they Coprime? No
LCM(48, 18) = 144
Step 1: 48 = (2 × 18) + 12
Step 2: 18 = (1 × 12) + 6
Step 3: 12 = (2 × 6) + 0 ← Remainder is 0, so GCD is 6
