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.
