Factor Pairs of 198

A Factor Pair of number 198 is a combination of two factors which can be multiplied together to equal 198.

List of all possible Factor Pairs of 198:

  • 1 × 198 = 198
  • 2 × 99 = 198
  • 3 × 66 = 198
  • 6 × 33 = 198
  • 9 × 22 = 198
  • 11 × 18 = 198

How to find the Factors of 198

Divide 198 by every whole number from 1 up to 14. Each division without a remainder gives a factor and its pair. There is no point going further: 15 × 15 = 225 is already greater than 198, so any larger divisor would pair with a smaller one you have already checked.

  • 198 ÷ 1 = 198 — factors 1 and 198
  • 198 ÷ 2 = 99 — factors 2 and 99
  • 198 ÷ 3 = 66 — factors 3 and 66
  • 198 ÷ 4 — remainder 2, not a factor
  • 198 ÷ 5 — remainder 3, not a factor
  • 198 ÷ 6 = 33 — factors 6 and 33
  • 198 ÷ 7 — remainder 2, not a factor
  • 198 ÷ 8 — remainder 6, not a factor
  • 198 ÷ 9 = 22 — factors 9 and 22
  • 198 ÷ 10 — remainder 8, not a factor
  • 198 ÷ 11 = 18 — factors 11 and 18
  • 198 ÷ 12 — remainder 6, not a factor
  • 198 ÷ 13 — remainder 3, not a factor
  • 198 ÷ 14 — remainder 2, not a factor

Why 198 has exactly 12 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.

198 = 2 × 32 × 11

(1 + 1) × (2 + 1) × (1 + 1) = 12

Step-by-step factorization: Prime factors of 198.
