The Greatest Common Divisor (GCD) is the largest positive integer that divides all given numbers without remainder. Example: GCD(12,18) = 6.
The Euclidean algorithm, the most efficient classical algorithm for computing GCD, with time complexity O(log min(a,b)).
Supports 2 to 20 numbers. Simply separate numbers with commas or spaces.
