Greatest common divisor

Largest integer that divides given integers

In mathematics, the greatest common divisor (GCD), also known as greatest common factor (GCF), of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted gcd ( x , y) {\displaystyle \gcd(x,y)} . For example, the GCD of 8 and 12 is 4, that is, gcd(8, 12) = 4.
