(number 620 has 12 factors)

Factor Pairs of 620

A Factor Pair of number 620 is a combination of two factors which can be multiplied together to equal 620.

List of all possible Factor Pairs of 620:

  • 1 × 620 = 620
  • 2 × 310 = 620
  • 4 × 155 = 620
  • 5 × 124 = 620
  • 10 × 62 = 620
  • 20 × 31 = 620

How to find the Factors of 620

Divide 620 by every whole number from 1 up to 24. Each division without a remainder gives a factor and its pair. There is no point going further: 25 × 25 = 625 is already greater than 620, so any larger divisor would pair with a smaller one you have already checked.

  • 620 ÷ 1 = 620 — factors 1 and 620
  • 620 ÷ 2 = 310 — factors 2 and 310
  • 620 ÷ 3 — remainder 2, not a factor
  • 620 ÷ 4 = 155 — factors 4 and 155
  • 620 ÷ 5 = 124 — factors 5 and 124
  • 620 ÷ 6 — remainder 2, not a factor
  • 620 ÷ 7 — remainder 4, not a factor
  • 620 ÷ 8 — remainder 4, not a factor
  • 620 ÷ 9 — remainder 8, not a factor
  • 620 ÷ 10 = 62 — factors 10 and 62
  • 620 ÷ 11 — remainder 4, not a factor
  • 620 ÷ 12 — remainder 8, not a factor
  • 620 ÷ 13 — remainder 9, not a factor
  • 620 ÷ 14 — remainder 4, not a factor
  • 620 ÷ 15 — remainder 5, not a factor
  • 620 ÷ 16 — remainder 12, not a factor
  • 620 ÷ 17 — remainder 8, not a factor
  • 620 ÷ 18 — remainder 8, not a factor
  • 620 ÷ 19 — remainder 12, not a factor
  • 620 ÷ 20 = 31 — factors 20 and 31
  • 620 ÷ 21 — remainder 11, not a factor
  • 620 ÷ 22 — remainder 4, not a factor
  • 620 ÷ 23 — remainder 22, not a factor
  • 620 ÷ 24 — remainder 20, not a factor

Why 620 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.

620 = 22 × 5 × 31

(2 + 1) × (1 + 1) × (1 + 1) = 12

Step-by-step factorization: Prime factors of 620.
