How to find the factors of 537

Test every whole number from 1 up to the square root of 537 (√537 ≈ 23.173). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

  • 537 ÷ 1 = 537 — so 1 and 537 are factors
  • 537 ÷ 2 = 268.5 — not a whole number
  • 537 ÷ 3 = 179 — so 3 and 179 are factors
  • 537 ÷ 4 = 134.25 — not a whole number
  • 537 ÷ 5 = 107.4 — not a whole number
  • 537 ÷ 6 = 89.5 — not a whole number
  • 537 ÷ 7 = 76.714 — not a whole number
  • 537 ÷ 8 = 67.125 — not a whole number
  • 537 ÷ 9 = 59.667 — not a whole number
  • 537 ÷ 10 = 53.7 — not a whole number
  • 537 ÷ 11 = 48.818 — not a whole number
  • 537 ÷ 12 = 44.75 — not a whole number
  • 537 ÷ 13 = 41.308 — not a whole number
  • 537 ÷ 14 = 38.357 — not a whole number
  • 537 ÷ 15 = 35.8 — not a whole number
  • 537 ÷ 16 = 33.563 — not a whole number
  • 537 ÷ 17 = 31.588 — not a whole number
  • 537 ÷ 18 = 29.833 — not a whole number
  • 537 ÷ 19 = 28.263 — not a whole number
  • 537 ÷ 20 = 26.85 — not a whole number
  • 537 ÷ 21 = 25.571 — not a whole number
  • 537 ÷ 22 = 24.409 — not a whole number
  • 537 ÷ 23 = 23.348 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 3, 179 and 537.

Prime factorization of 537

Divide by the smallest prime that fits, and keep going until the quotient is 1:

537 ÷ 3 = 179
179 ÷ 179 = 1

The primes you divided by give 537 = 3 × 179. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) = 4.

Properties of 537
