Factors of 315:
1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
(number 315 has 12 factors)
Factor Pairs of 315
A Factor Pair of number 315 is a combination of two factors which can be multiplied together to equal 315.
List of all possible Factor Pairs of 315:
- 1 × 315 = 315
- 3 × 105 = 315
- 5 × 63 = 315
- 7 × 45 = 315
- 9 × 35 = 315
- 15 × 21 = 315
How to find the Factors of 315
Divide 315 by every whole number from 1 up to 17. Each division without a remainder gives a factor and its pair. There is no point going further: 18 × 18 = 324 is already greater than 315, so any larger divisor would pair with a smaller one you have already checked.
- 315 ÷ 1 = 315 — factors 1 and 315
- 315 ÷ 2 — remainder 1, not a factor
- 315 ÷ 3 = 105 — factors 3 and 105
- 315 ÷ 4 — remainder 3, not a factor
- 315 ÷ 5 = 63 — factors 5 and 63
- 315 ÷ 6 — remainder 3, not a factor
- 315 ÷ 7 = 45 — factors 7 and 45
- 315 ÷ 8 — remainder 3, not a factor
- 315 ÷ 9 = 35 — factors 9 and 35
- 315 ÷ 10 — remainder 5, not a factor
- 315 ÷ 11 — remainder 7, not a factor
- 315 ÷ 12 — remainder 3, not a factor
- 315 ÷ 13 — remainder 3, not a factor
- 315 ÷ 14 — remainder 7, not a factor
- 315 ÷ 15 = 21 — factors 15 and 21
- 315 ÷ 16 — remainder 11, not a factor
- 315 ÷ 17 — remainder 9, not a factor
Why 315 has exactly 12 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.
315 = 32 × 5 × 7
(2 + 1) × (1 + 1) × (1 + 1) = 12
Step-by-step factorization: Prime factors of 315.
