How to find the factors of 471

Test every whole number from 1 up to the square root of 471 (√471 ≈ 21.703). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

  • 471 ÷ 1 = 471 — so 1 and 471 are factors
  • 471 ÷ 2 = 235.5 — not a whole number
  • 471 ÷ 3 = 157 — so 3 and 157 are factors
  • 471 ÷ 4 = 117.75 — not a whole number
  • 471 ÷ 5 = 94.2 — not a whole number
  • 471 ÷ 6 = 78.5 — not a whole number
  • 471 ÷ 7 = 67.286 — not a whole number
  • 471 ÷ 8 = 58.875 — not a whole number
  • 471 ÷ 9 = 52.333 — not a whole number
  • 471 ÷ 10 = 47.1 — not a whole number
  • 471 ÷ 11 = 42.818 — not a whole number
  • 471 ÷ 12 = 39.25 — not a whole number
  • 471 ÷ 13 = 36.231 — not a whole number
  • 471 ÷ 14 = 33.643 — not a whole number
  • 471 ÷ 15 = 31.4 — not a whole number
  • 471 ÷ 16 = 29.438 — not a whole number
  • 471 ÷ 17 = 27.706 — not a whole number
  • 471 ÷ 18 = 26.167 — not a whole number
  • 471 ÷ 19 = 24.789 — not a whole number
  • 471 ÷ 20 = 23.55 — not a whole number
  • 471 ÷ 21 = 22.429 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 3, 157 and 471.

Prime factorization of 471

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

471 ÷ 3 = 157
157 ÷ 157 = 1

The primes you divided by give 471 = 3 × 157. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) = 4.

Properties of 471
