How to find the factors of 560
Test every whole number from 1 up to the square root of 560 (√560 ≈ 23.664). Each number that divides evenly gives you two factors at once: the divisor and the quotient.
- 560 ÷ 1 = 560 — so 1 and 560 are factors
- 560 ÷ 2 = 280 — so 2 and 280 are factors
- 560 ÷ 3 = 186.667 — not a whole number
- 560 ÷ 4 = 140 — so 4 and 140 are factors
- 560 ÷ 5 = 112 — so 5 and 112 are factors
- 560 ÷ 6 = 93.333 — not a whole number
- 560 ÷ 7 = 80 — so 7 and 80 are factors
- 560 ÷ 8 = 70 — so 8 and 70 are factors
- 560 ÷ 9 = 62.222 — not a whole number
- 560 ÷ 10 = 56 — so 10 and 56 are factors
- 560 ÷ 11 = 50.909 — not a whole number
- 560 ÷ 12 = 46.667 — not a whole number
- 560 ÷ 13 = 43.077 — not a whole number
- 560 ÷ 14 = 40 — so 14 and 40 are factors
- 560 ÷ 15 = 37.333 — not a whole number
- 560 ÷ 16 = 35 — so 16 and 35 are factors
- 560 ÷ 17 = 32.941 — not a whole number
- 560 ÷ 18 = 31.111 — not a whole number
- 560 ÷ 19 = 29.474 — not a whole number
- 560 ÷ 20 = 28 — so 20 and 28 are factors
- 560 ÷ 21 = 26.667 — not a whole number
- 560 ÷ 22 = 25.455 — not a whole number
- 560 ÷ 23 = 24.348 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280 and 560.
Prime factorization of 560
