Factor Pairs of 57

A Factor Pair of number 57 is a combination of two factors which can be multiplied together to equal 57.

List of all possible Factor Pairs of 57:

  • 1 × 57 = 57
  • 3 × 19 = 57

How to find the Factors of 57

Divide 57 by every whole number from 1 up to 7. Each division without a remainder gives a factor and its pair. There is no point going further: 8 × 8 = 64 is already greater than 57, so any larger divisor would pair with a smaller one you have already checked.

  • 57 ÷ 1 = 57 — factors 1 and 57
  • 57 ÷ 2 — remainder 1, not a factor
  • 57 ÷ 3 = 19 — factors 3 and 19
  • 57 ÷ 4 — remainder 1, not a factor
  • 57 ÷ 5 — remainder 2, not a factor
  • 57 ÷ 6 — remainder 3, not a factor
  • 57 ÷ 7 — remainder 1, not a factor

Why 57 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.

57 = 3 × 19

(1 + 1) × (1 + 1) = 4

Step-by-step factorization: Prime factors of 57.
