The GCD of a and b is generally denoted gcd(a, b). This definition … 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. For example, gcd(42, 56) = 14, therefore, See more • 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 … See more The notion of greatest common divisor can more generally be defined for elements of an arbitrary commutative ring, although in general there need not exist one for every pair of elements.
