Divisors are a fundamental concept in number theory. The set of a number's divisors consists of all natural numbers that divide it evenly leaving no remainder. Members of a number's divisor set are said to divide the number. Wolfram|Alpha can compute divisors, greatest common divisors, least common multiples and more related values.
Compute the divisors of numbers or test divisibility.
Extract common divisors, compute greatest common divisors or compute least common multiples of pairs or lists of numbers.
