1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
(number 280 has 16 factors)
Factor Pairs of 280
A Factor Pair of number 280 is a combination of two factors which can be multiplied together to equal 280.
List of all possible Factor Pairs of 280:
- 1 × 280 = 280
- 2 × 140 = 280
- 4 × 70 = 280
- 5 × 56 = 280
- 7 × 40 = 280
- 8 × 35 = 280
- 10 × 28 = 280
- 14 × 20 = 280
How to find the Factors of 280
Divide 280 by every whole number from 1 up to 16. Each division without a remainder gives a factor and its pair. There is no point going further: 17 × 17 = 289 is already greater than 280, so any larger divisor would pair with a smaller one you have already checked.
- 280 ÷ 1 = 280 — factors 1 and 280
- 280 ÷ 2 = 140 — factors 2 and 140
- 280 ÷ 3 — remainder 1, not a factor
- 280 ÷ 4 = 70 — factors 4 and 70
- 280 ÷ 5 = 56 — factors 5 and 56
- 280 ÷ 6 — remainder 4, not a factor
- 280 ÷ 7 = 40 — factors 7 and 40
- 280 ÷ 8 = 35 — factors 8 and 35
- 280 ÷ 9 — remainder 1, not a factor
- 280 ÷ 10 = 28 — factors 10 and 28
- 280 ÷ 11 — remainder 5, not a factor
- 280 ÷ 12 — remainder 4, not a factor
- 280 ÷ 13 — remainder 7, not a factor
- 280 ÷ 14 = 20 — factors 14 and 20
- 280 ÷ 15 — remainder 10, not a factor
- 280 ÷ 16 — remainder 8, not a factor
Why 280 has exactly 16 factors
The count follows from the prime factorization: add 1 to each exponent and multiply. Counting the divisors this way needs no trial division at all, however large the number is.
280 = 23 × 5 × 7
(3 + 1) × (1 + 1) × (1 + 1) = 16
Step-by-step factorization: Prime factors of 280.
