What is GCD of two numbers ? jump to gcd calc
GCD of two numbers A and B is the highest number that exactly divides the two.
Full Form of GCD : greatest common divisor
Find the gcd using this calculator. The result is always positive even if either of, or both, input numbers A and B are negative.
Let's see an example of GCD when A = 20 and B = 12 . the greatest number that divides both 20 and 12 is 4. as 20/4 = 5, and 12/4 = 3, there is no remainder.
Enter A and B, to find gcd(A, B).
