Table of divisors

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

Plot of the number of divisors of integers from 1 to 1000. Highly composite numbers are in bold.

A divisor of an integer n is an integer m, 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 21/7 = 3 (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 the positive divisors of n, including 1 and n itself
s(n) is the sum of the proper divisors of n, including 1, but not n itself; that is, s(n) = σ(n) − n
a deficient number is greater than the sum of its proper divisors; that is, s(n) < n
a perfect number equals the sum of its proper divisors; that is, s(n) = n
an abundant number is lesser than the sum of its proper divisors; that is, s(n) > n
a highly abundant number has a sum of proper divisors greater than any lesser number's sum of proper divisors; that is, s(n) > s(m) for every positive integer m < n

note: confusingly, the first seven highly abundant numbers aren't even abundant numbers

a prime number has only 1 and itself as divisors; that is, d(n) = 2. Prime numbers are always deficient as s(n)=1
a composite number has more than just 1 and itself as divisors; that is, d(n) > 2
a highly composite number has more divisors than any lesser number; that is, d(n) > d(m) for every positive integer m < n

note: confusingly, the first two highly composite numbers aren't even composite numbers

a superior highly composite number has more divisors than any other number scaled relative to some positive power of the number itself; that is, there exists some ε such that ${\frac {d(n)}{n^{\varepsilon }}}>{\frac {d(m)}{m^{\varepsilon }}}$ for every other positive integer m. Superior highly composite numbers are always highly composite numbers
a weird number is an abundant number that is not semiperfect; that is, no subset of the proper divisors of n sum to n
