List of all possible Factor Pairs of 489:

  • 1 × 489 = 489
  • 3 × 163 = 489

How to find the Factors of 489

Divide 489 by every whole number from 1 up to 22. Each division without a remainder gives a factor and its pair. There is no point going further: 23 × 23 = 529 is already greater than 489, so any larger divisor would pair with a smaller one you have already checked.

  • 489 ÷ 1 = 489 — factors 1 and 489
  • 489 ÷ 2 — remainder 1, not a factor
  • 489 ÷ 3 = 163 — factors 3 and 163
  • 489 ÷ 4 — remainder 1, not a factor
  • 489 ÷ 5 — remainder 4, not a factor
  • 489 ÷ 6 — remainder 3, not a factor
  • 489 ÷ 7 — remainder 6, not a factor
  • 489 ÷ 8 — remainder 1, not a factor
  • 489 ÷ 9 — remainder 3, not a factor
  • 489 ÷ 10 — remainder 9, not a factor
  • 489 ÷ 11 — remainder 5, not a factor
  • 489 ÷ 12 — remainder 9, not a factor
  • 489 ÷ 13 — remainder 8, not a factor
  • 489 ÷ 14 — remainder 13, not a factor
  • 489 ÷ 15 — remainder 9, not a factor
  • 489 ÷ 16 — remainder 9, not a factor
  • 489 ÷ 17 — remainder 13, not a factor
  • 489 ÷ 18 — remainder 3, not a factor
  • 489 ÷ 19 — remainder 14, not a factor
  • 489 ÷ 20 — remainder 9, not a factor
  • 489 ÷ 21 — remainder 6, not a factor
