How to find the factors of 480
Test every whole number from 1 up to the square root of 480 (√480 ≈ 21.909). Each number that divides evenly gives you two factors at once: the divisor and the quotient.
- 480 ÷ 1 = 480 — so 1 and 480 are factors
- 480 ÷ 2 = 240 — so 2 and 240 are factors
- 480 ÷ 3 = 160 — so 3 and 160 are factors
- 480 ÷ 4 = 120 — so 4 and 120 are factors
- 480 ÷ 5 = 96 — so 5 and 96 are factors
- 480 ÷ 6 = 80 — so 6 and 80 are factors
- 480 ÷ 7 = 68.571 — not a whole number
- 480 ÷ 8 = 60 — so 8 and 60 are factors
- 480 ÷ 9 = 53.333 — not a whole number
- 480 ÷ 10 = 48 — so 10 and 48 are factors
- 480 ÷ 11 = 43.636 — not a whole number
- 480 ÷ 12 = 40 — so 12 and 40 are factors
- 480 ÷ 13 = 36.923 — not a whole number
- 480 ÷ 14 = 34.286 — not a whole number
- 480 ÷ 15 = 32 — so 15 and 32 are factors
- 480 ÷ 16 = 30 — so 16 and 30 are factors
- 480 ÷ 17 = 28.235 — not a whole number
- 480 ÷ 18 = 26.667 — not a whole number
- 480 ÷ 19 = 25.263 — not a whole number
- 480 ÷ 20 = 24 — so 20 and 24 are factors
- 480 ÷ 21 = 22.857 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240 and 480.
Prime factorization of 480
Divide by the smallest prime that fits, and keep going until the quotient is 1:
The primes you divided by give 480 = 2⁵ × 3 × 5. From the exponents you can also count the factors without listing them: (5 + 1) × (1 + 1) × (1 + 1) = 24.
Properties of 480
- 480 is a composite number.
- The sum of all its factors is 1,512; the sum of its proper factors (excluding 480) is 1,032, which makes it a abundant number (its proper factors add up to more than itself).
- 480 is not a perfect square, so its factors pair up evenly.
- Multiples of 480 include 960, 1,440, 1,920, 2,400 and so on.
