(number 240 has 20 factors)
Factor Pairs of 240
A Factor Pair of number 240 is a combination of two factors which can be multiplied together to equal 240.
List of all possible Factor Pairs of 240:
- 1 × 240 = 240
- 2 × 120 = 240
- 3 × 80 = 240
- 4 × 60 = 240
- 5 × 48 = 240
- 6 × 40 = 240
- 8 × 30 = 240
- 10 × 24 = 240
- 12 × 20 = 240
- 15 × 16 = 240
How to find the Factors of 240
Divide 240 by every whole number from 1 up to 15. Each division without a remainder gives a factor and its pair. There is no point going further: 16 × 16 = 256 is already greater than 240, so any larger divisor would pair with a smaller one you have already checked.
- 240 ÷ 1 = 240 — factors 1 and 240
- 240 ÷ 2 = 120 — factors 2 and 120
- 240 ÷ 3 = 80 — factors 3 and 80
- 240 ÷ 4 = 60 — factors 4 and 60
- 240 ÷ 5 = 48 — factors 5 and 48
- 240 ÷ 6 = 40 — factors 6 and 40
- 240 ÷ 7 — remainder 2, not a factor
- 240 ÷ 8 = 30 — factors 8 and 30
- 240 ÷ 9 — remainder 6, not a factor
- 240 ÷ 10 = 24 — factors 10 and 24
- 240 ÷ 11 — remainder 9, not a factor
- 240 ÷ 12 = 20 — factors 12 and 20
- 240 ÷ 13 — remainder 6, not a factor
- 240 ÷ 14 — remainder 2, not a factor
- 240 ÷ 15 = 16 — factors 15 and 16
Why 240 has exactly 20 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.
240 = 24 × 3 × 5
(4 + 1) × (1 + 1) × (1 + 1) = 20
Step-by-step factorization: Prime factors of 240.
