Factor Pairs of 440

A Factor Pair of number 440 is a combination of two factors which can be multiplied together to equal 440.

List of all possible Factor Pairs of 440:

  • 1 × 440 = 440
  • 2 × 220 = 440
  • 4 × 110 = 440
  • 5 × 88 = 440
  • 8 × 55 = 440
  • 10 × 44 = 440
  • 11 × 40 = 440
  • 20 × 22 = 440

How to find the Factors of 440

Divide 440 by every whole number from 1 up to 20. Each division without a remainder gives a factor and its pair. There is no point going further: 21 × 21 = 441 is already greater than 440, so any larger divisor would pair with a smaller one you have already checked.

  • 440 ÷ 1 = 440 — factors 1 and 440
  • 440 ÷ 2 = 220 — factors 2 and 220
  • 440 ÷ 3 — remainder 2, not a factor
  • 440 ÷ 4 = 110 — factors 4 and 110
  • 440 ÷ 5 = 88 — factors 5 and 88
  • 440 ÷ 6 — remainder 2, not a factor
  • 440 ÷ 7 — remainder 6, not a factor
  • 440 ÷ 8 = 55 — factors 8 and 55
  • 440 ÷ 9 — remainder 8, not a factor
  • 440 ÷ 10 = 44 — factors 10 and 44
  • 440 ÷ 11 = 40 — factors 11 and 40
  • 440 ÷ 12 — remainder 8, not a factor
  • 440 ÷ 13 — remainder 11, not a factor
  • 440 ÷ 14 — remainder 6, not a factor
  • 440 ÷ 15 — remainder 5, not a factor
  • 440 ÷ 16 — remainder 8, not a factor
  • 440 ÷ 17 — remainder 15, not a factor
  • 440 ÷ 18 — remainder 8, not a factor
  • 440 ÷ 19 — remainder 3, not a factor
  • 440 ÷ 20 = 22 — factors 20 and 22

Why 440 has exactly 16 factors

The count follows from the prime factorization: add 1 to each exponent and multiply. Counting the divisors this way needs no trial division at all, however large the number is.

440 = 23 × 5 × 11

(3 + 1) × (1 + 1) × (1 + 1) = 16

Step-by-step factorization: Prime factors of 440.
