Every common divisor of a and b is a divisor of gcd(a, b).gcd(a, b), where a and b are not both zero, may be defined alternatively and equivalently as the smallest positive integer d which can be written in the form d = a⋅p + b⋅q, where p and q are integers. This expression is called Bézout's identity. Numbers p and q like … See more In mathematics, the greatest common divisor (GCD) 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 … See more Reducing fractions The greatest common divisor is useful for reducing fractions to the lowest terms.

It is also known as Euclid's Algorithm. The algorithm states that: If A=0 then GCD (A,B)=B, since the GCD (0,B)=B, and we can exit from the algorithm. If B=0 then GCD (A,B)=A, since the GCD (A,0)=A, and we can exit from the algorithm.
