Factor Pairs of 99

A Factor Pair of number 99 is a combination of two factors which can be multiplied together to equal 99.

List of all possible Factor Pairs of 99:

  • 1 × 99 = 99
  • 3 × 33 = 99
  • 9 × 11 = 99

How to find the Factors of 99

Divide 99 by every whole number from 1 up to 9. Each division without a remainder gives a factor and its pair. There is no point going further: 10 × 10 = 100 is already greater than 99, so any larger divisor would pair with a smaller one you have already checked.

  • 99 ÷ 1 = 99 — factors 1 and 99
  • 99 ÷ 2 — remainder 1, not a factor
  • 99 ÷ 3 = 33 — factors 3 and 33
  • 99 ÷ 4 — remainder 3, not a factor
  • 99 ÷ 5 — remainder 4, not a factor
  • 99 ÷ 6 — remainder 3, not a factor
  • 99 ÷ 7 — remainder 1, not a factor
  • 99 ÷ 8 — remainder 3, not a factor
  • 99 ÷ 9 = 11 — factors 9 and 11

Why 99 has exactly 6 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.

99 = 32 × 11

(2 + 1) × (1 + 1) = 6

Step-by-step factorization: Prime factors of 99.
