Factor Pairs of 340

A Factor Pair of number 340 is a combination of two factors which can be multiplied together to equal 340.

List of all possible Factor Pairs of 340:

  • 1 × 340 = 340
  • 2 × 170 = 340
  • 4 × 85 = 340
  • 5 × 68 = 340
  • 10 × 34 = 340
  • 17 × 20 = 340

How to find the Factors of 340

Divide 340 by every whole number from 1 up to 18. Each division without a remainder gives a factor and its pair. There is no point going further: 19 × 19 = 361 is already greater than 340, so any larger divisor would pair with a smaller one you have already checked.

  • 340 ÷ 1 = 340 — factors 1 and 340
  • 340 ÷ 2 = 170 — factors 2 and 170
  • 340 ÷ 3 — remainder 1, not a factor
  • 340 ÷ 4 = 85 — factors 4 and 85
  • 340 ÷ 5 = 68 — factors 5 and 68
  • 340 ÷ 6 — remainder 4, not a factor
  • 340 ÷ 7 — remainder 4, not a factor
  • 340 ÷ 8 — remainder 4, not a factor
  • 340 ÷ 9 — remainder 7, not a factor
  • 340 ÷ 10 = 34 — factors 10 and 34
  • 340 ÷ 11 — remainder 10, not a factor
  • 340 ÷ 12 — remainder 4, not a factor
  • 340 ÷ 13 — remainder 2, not a factor
  • 340 ÷ 14 — remainder 4, not a factor
  • 340 ÷ 15 — remainder 10, not a factor
  • 340 ÷ 16 — remainder 4, not a factor
  • 340 ÷ 17 = 20 — factors 17 and 20
  • 340 ÷ 18 — remainder 16, not a factor

Why 340 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.

340 = 22 × 5 × 17

(2 + 1) × (1 + 1) × (1 + 1) = 12

Step-by-step factorization: Prime factors of 340.
