What is GCD?
The Greatest Common Divisor (GCD) is the largest number that exactly divides two or more integers. Calculated by the Euclidean algorithm: divide the larger by the smaller, then repeat with the divisor and remainder until the remainder is zero.
Example: GCD(12, 8) → 12 = 1×8 + 4 → 8 = 2×4 + 0 → GCD = 4.
