WebFeb 1, 2024 · The greatest common divisor (GCD), also known as greatest common factor is the largest integer that divides evenly into each number in a given set. Formally, we define the (GCD) as follows: Let a and b be integers. Definition The greatest common divisor (GCD) of two nonzero integers a and b is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer. The GCD of a and b is generally denoted gcd(a, b). This definition also … 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 integer d which can be written in the form d = a⋅p + b⋅q, where p and q are integers. … See more • Bézout domain • Lowest common denominator • Unitary divisor See more Using prime factorizations Greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors. … See more In 1972, James E. Nymann showed that k integers, chosen independently and uniformly from {1, ..., n}, are coprime with probability 1/ζ(k) as n goes to infinity, where ζ refers to the 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.
