Factor Pairs of 120

A Factor Pair of number 120 is a combination of two factors which can be multiplied together to equal 120.

List of all possible Factor Pairs of 120:

  • 1 × 120 = 120
  • 2 × 60 = 120
  • 3 × 40 = 120
  • 4 × 30 = 120
  • 5 × 24 = 120
  • 6 × 20 = 120
  • 8 × 15 = 120
  • 10 × 12 = 120

How to find the Factors of 120

Divide 120 by every whole number from 1 up to 10. Each division without a remainder gives a factor and its pair. There is no point going further: 11 × 11 = 121 is already greater than 120, so any larger divisor would pair with a smaller one you have already checked.

  • 120 ÷ 1 = 120 — factors 1 and 120
  • 120 ÷ 2 = 60 — factors 2 and 60
  • 120 ÷ 3 = 40 — factors 3 and 40
  • 120 ÷ 4 = 30 — factors 4 and 30
  • 120 ÷ 5 = 24 — factors 5 and 24
  • 120 ÷ 6 = 20 — factors 6 and 20
  • 120 ÷ 7 — remainder 1, not a factor
  • 120 ÷ 8 = 15 — factors 8 and 15
  • 120 ÷ 9 — remainder 3, not a factor
  • 120 ÷ 10 = 12 — factors 10 and 12

Why 120 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.

120 = 23 × 3 × 5

(3 + 1) × (1 + 1) × (1 + 1) = 16

Step-by-step factorization: Prime factors of 120.
