Factor Pairs of 320

A Factor Pair of number 320 is a combination of two factors which can be multiplied together to equal 320.

List of all possible Factor Pairs of 320:

  • 1 × 320 = 320
  • 2 × 160 = 320
  • 4 × 80 = 320
  • 5 × 64 = 320
  • 8 × 40 = 320
  • 10 × 32 = 320
  • 16 × 20 = 320

How to find the Factors of 320

Divide 320 by every whole number from 1 up to 17. Each division without a remainder gives a factor and its pair. There is no point going further: 18 × 18 = 324 is already greater than 320, so any larger divisor would pair with a smaller one you have already checked.

  • 320 ÷ 1 = 320 — factors 1 and 320
  • 320 ÷ 2 = 160 — factors 2 and 160
  • 320 ÷ 3 — remainder 2, not a factor
  • 320 ÷ 4 = 80 — factors 4 and 80
  • 320 ÷ 5 = 64 — factors 5 and 64
  • 320 ÷ 6 — remainder 2, not a factor
  • 320 ÷ 7 — remainder 5, not a factor
  • 320 ÷ 8 = 40 — factors 8 and 40
  • 320 ÷ 9 — remainder 5, not a factor
  • 320 ÷ 10 = 32 — factors 10 and 32
  • 320 ÷ 11 — remainder 1, not a factor
  • 320 ÷ 12 — remainder 8, not a factor
  • 320 ÷ 13 — remainder 8, not a factor
  • 320 ÷ 14 — remainder 12, not a factor
  • 320 ÷ 15 — remainder 5, not a factor
  • 320 ÷ 16 = 20 — factors 16 and 20
  • 320 ÷ 17 — remainder 14, not a factor

Why 320 has exactly 14 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.

320 = 26 × 5

(6 + 1) × (1 + 1) = 14

Step-by-step factorization: Prime factors of 320.
