How to find the factors of 774

Test every whole number from 1 up to the square root of 774 (√774 ≈ 27.821). Each number that divides evenly gives you two factors at once: the divisor and the quotient.

  • 774 ÷ 1 = 774 — so 1 and 774 are factors
  • 774 ÷ 2 = 387 — so 2 and 387 are factors
  • 774 ÷ 3 = 258 — so 3 and 258 are factors
  • 774 ÷ 4 = 193.5 — not a whole number
  • 774 ÷ 5 = 154.8 — not a whole number
  • 774 ÷ 6 = 129 — so 6 and 129 are factors
  • 774 ÷ 7 = 110.571 — not a whole number
  • 774 ÷ 8 = 96.75 — not a whole number
  • 774 ÷ 9 = 86 — so 9 and 86 are factors
  • 774 ÷ 10 = 77.4 — not a whole number
  • 774 ÷ 11 = 70.364 — not a whole number
  • 774 ÷ 12 = 64.5 — not a whole number
  • 774 ÷ 13 = 59.538 — not a whole number
  • 774 ÷ 14 = 55.286 — not a whole number
  • 774 ÷ 15 = 51.6 — not a whole number
  • 774 ÷ 16 = 48.375 — not a whole number
  • 774 ÷ 17 = 45.529 — not a whole number
  • 774 ÷ 18 = 43 — so 18 and 43 are factors
  • 774 ÷ 19 = 40.737 — not a whole number
  • 774 ÷ 20 = 38.7 — not a whole number
  • 774 ÷ 21 = 36.857 — not a whole number
  • 774 ÷ 22 = 35.182 — not a whole number
  • 774 ÷ 23 = 33.652 — not a whole number
  • 774 ÷ 24 = 32.25 — not a whole number
  • 774 ÷ 25 = 30.96 — not a whole number
  • 774 ÷ 26 = 29.769 — not a whole number
  • 774 ÷ 27 = 28.667 — not a whole number

Collecting both numbers from every successful division gives the complete list: 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387 and 774.

Prime factorization of 774

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

774 ÷ 2 = 387
387 ÷ 3 = 129
129 ÷ 3 = 43
43 ÷ 43 = 1

The primes you divided by give 774 = 2 × 3² × 43. From the exponents you can also count the factors without listing them: (1 + 1) × (2 + 1) × (1 + 1) = 12.

Properties of 774
