What is the GCD? The GCD (short for greater common divisor) is a useful mathematical concept: it is the largest number that divides exactly all the numbers in a set. The GCD is defined for every …

The greatest common divisor (GCD), also called the greatest common factor, of two numbers is the largest number that divides them both. For instance, the greatest common factor of 20 and 15 is 5, …

The GCD is sometimes called the greatest common factor (GCF). A very useful property of the GCD is that it can be represented as a sum of the given numbers with integer coefficients.
