Factor Pairs of 450

A Factor Pair of number 450 is a combination of two factors which can be multiplied together to equal 450.

List of all possible Factor Pairs of 450:

  • 1 × 450 = 450
  • 2 × 225 = 450
  • 3 × 150 = 450
  • 5 × 90 = 450
  • 6 × 75 = 450
  • 9 × 50 = 450
  • 10 × 45 = 450
  • 15 × 30 = 450

How to find the Factors of 450

Divide 450 by every whole number from 1 up to 21. Each division without a remainder gives a factor and its pair. There is no point going further: 22 × 22 = 484 is already greater than 450, so any larger divisor would pair with a smaller one you have already checked.

  • 450 ÷ 1 = 450 — factors 1 and 450
  • 450 ÷ 2 = 225 — factors 2 and 225
  • 450 ÷ 3 = 150 — factors 3 and 150
  • 450 ÷ 4 — remainder 2, not a factor
  • 450 ÷ 5 = 90 — factors 5 and 90
  • 450 ÷ 6 = 75 — factors 6 and 75
  • 450 ÷ 7 — remainder 2, not a factor
  • 450 ÷ 8 — remainder 2, not a factor
  • 450 ÷ 9 = 50 — factors 9 and 50
  • 450 ÷ 10 = 45 — factors 10 and 45
  • 450 ÷ 11 — remainder 10, not a factor
  • 450 ÷ 12 — remainder 6, not a factor
  • 450 ÷ 13 — remainder 8, not a factor
  • 450 ÷ 14 — remainder 2, not a factor
  • 450 ÷ 15 = 30 — factors 15 and 30
  • 450 ÷ 16 — remainder 2, not a factor
  • 450 ÷ 17 — remainder 8, not a factor
  • 450 ÷ 18 = 25 — factors 18 and 25
  • 450 ÷ 19 — remainder 13, not a factor
  • 450 ÷ 20 — remainder 10, not a factor
  • 450 ÷ 21 — remainder 9, not a factor

Why 450 has exactly 18 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.

450 = 2 × 32 × 52

(1 + 1) × (2 + 1) × (2 + 1) = 18

Step-by-step factorization: Prime factors of 450.
