Table of divisors Guide, Meaning , Facts, Information and Description

The tables below list all of the divisors of the numbers 1 to 1000.

A divisor of an integer n is an integer m, say, for which n/m is again an integer (which is necessarily also a divisor of n). For example, 3 is a divisor of 21, since 21/3 = 7 (and 7 is also a divisor of 21).

If m is a divisor of n then so is −m. The tables below only list positive divisors.

Key to the tables

• d(n) is the number of positive divisors of n, including 1 and n itself
• σ(n) is the sum of all the positive divisors of n, including 1 and n itself
• s(n) is the sum of the proper divisors of n, which does not include n itself
• a perfect number equals the sum of its proper divisors; that is, s(n) = n; the only perfect numbers between 1 and 1000 are 6, 28 and 496
• a deficient number is less than the sum of its proper divisors; that is, s(n) < n
• an abundant number is greater than the sum of its proper divisors; that is, s(n) > n
• a prime number has only 1 and itself as divisors; that is, d(n) = 2
