Factor Pairs of 308

A Factor Pair of number 308 is a combination of two factors which can be multiplied together to equal 308.

List of all possible Factor Pairs of 308:

  • 1 × 308 = 308
  • 2 × 154 = 308
  • 4 × 77 = 308
  • 7 × 44 = 308
  • 11 × 28 = 308
  • 14 × 22 = 308

How to find the Factors of 308

Divide 308 by every whole number from 1 up to 17. Each division without a remainder gives a factor and its pair. There is no point going further: 18 × 18 = 324 is already greater than 308, so any larger divisor would pair with a smaller one you have already checked.

  • 308 ÷ 1 = 308 — factors 1 and 308
  • 308 ÷ 2 = 154 — factors 2 and 154
  • 308 ÷ 3 — remainder 2, not a factor
  • 308 ÷ 4 = 77 — factors 4 and 77
  • 308 ÷ 5 — remainder 3, not a factor
  • 308 ÷ 6 — remainder 2, not a factor
  • 308 ÷ 7 = 44 — factors 7 and 44
  • 308 ÷ 8 — remainder 4, not a factor
  • 308 ÷ 9 — remainder 2, not a factor
  • 308 ÷ 10 — remainder 8, not a factor
  • 308 ÷ 11 = 28 — factors 11 and 28
  • 308 ÷ 12 — remainder 8, not a factor
  • 308 ÷ 13 — remainder 9, not a factor
  • 308 ÷ 14 = 22 — factors 14 and 22
  • 308 ÷ 15 — remainder 8, not a factor
  • 308 ÷ 16 — remainder 4, not a factor
  • 308 ÷ 17 — remainder 2, not a factor

Why 308 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.

308 = 22 × 7 × 11

(2 + 1) × (1 + 1) × (1 + 1) = 12

Step-by-step factorization: Prime factors of 308.
