Factor Pairs of 158

A Factor Pair of number 158 is a combination of two factors which can be multiplied together to equal 158.

List of all possible Factor Pairs of 158:

  • 1 × 158 = 158
  • 2 × 79 = 158

How to find the Factors of 158

Divide 158 by every whole number from 1 up to 12. Each division without a remainder gives a factor and its pair. There is no point going further: 13 × 13 = 169 is already greater than 158, so any larger divisor would pair with a smaller one you have already checked.

  • 158 ÷ 1 = 158 — factors 1 and 158
  • 158 ÷ 2 = 79 — factors 2 and 79
  • 158 ÷ 3 — remainder 2, not a factor
  • 158 ÷ 4 — remainder 2, not a factor
  • 158 ÷ 5 — remainder 3, not a factor
  • 158 ÷ 6 — remainder 2, not a factor
  • 158 ÷ 7 — remainder 4, not a factor
  • 158 ÷ 8 — remainder 6, not a factor
  • 158 ÷ 9 — remainder 5, not a factor
  • 158 ÷ 10 — remainder 8, not a factor
  • 158 ÷ 11 — remainder 4, not a factor
  • 158 ÷ 12 — remainder 2, not a factor

Why 158 has exactly 4 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.

158 = 2 × 79

(1 + 1) × (1 + 1) = 4

Step-by-step factorization: Prime factors of 158.
