Factors of 345:
1, 3, 5, 15, 23, 69, 115, 345
(number 345 has 8 factors)
Factor Pairs of 345
A Factor Pair of number 345 is a combination of two factors which can be multiplied together to equal 345.
List of all possible Factor Pairs of 345:
- 1 × 345 = 345
- 3 × 115 = 345
- 5 × 69 = 345
- 15 × 23 = 345
How to find the Factors of 345
Divide 345 by every whole number from 1 up to 18. Each division without a remainder gives a factor and its pair. There is no point going further: 19 × 19 = 361 is already greater than 345, so any larger divisor would pair with a smaller one you have already checked.
- 345 ÷ 1 = 345 — factors 1 and 345
- 345 ÷ 2 — remainder 1, not a factor
- 345 ÷ 3 = 115 — factors 3 and 115
- 345 ÷ 4 — remainder 1, not a factor
- 345 ÷ 5 = 69 — factors 5 and 69
- 345 ÷ 6 — remainder 3, not a factor
- 345 ÷ 7 — remainder 2, not a factor
- 345 ÷ 8 — remainder 1, not a factor
- 345 ÷ 9 — remainder 3, not a factor
- 345 ÷ 10 — remainder 5, not a factor
- 345 ÷ 11 — remainder 4, not a factor
- 345 ÷ 12 — remainder 9, not a factor
- 345 ÷ 13 — remainder 7, not a factor
- 345 ÷ 14 — remainder 9, not a factor
- 345 ÷ 15 = 23 — factors 15 and 23
- 345 ÷ 16 — remainder 9, not a factor
- 345 ÷ 17 — remainder 5, not a factor
- 345 ÷ 18 — remainder 3, not a factor
Why 345 has exactly 8 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.
345 = 3 × 5 × 23
(1 + 1) × (1 + 1) × (1 + 1) = 8
Step-by-step factorization: Prime factors of 345.
