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

Key to the tables Edit

  • 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, which does not include n itself; that is, s(n) = σ(n) − n
  • φ(n) is the number of the nonnegative integers < n that are relatively prime to n
  • sopf(n) is the sum of the distinct primes dividing n
  • sopfr(n) is the sum of primes dividing n, with repetition

(Ruth-Aaron pair has two definitions: sopf(n) = sopf(n+1) and sopfr(n) = sopfr(n+1))

  • a perfect number equals the sum of its proper divisors; that is, s(n) = n
  • a deficient number is greater than 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 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 2 divisors; that is, d(n) > 2
  • a sublime number has a perfect number of divisors, that is d(n) = perfect number, and whose divisors add up to another perfect number, that is σ(n) = perfect number
