What are the Factors of 231?
Answer
Factors of 231:
1, 3, 7, 11, 21, 33, 77, 231
(number 231 has 8 factors)
Factor Pairs of 231
A Factor Pair of number 231 is a combination of two factors which can be multiplied together to equal 231.
List of all possible Factor Pairs of 231:
- 1 × 231 = 231
- 3 × 77 = 231
- 7 × 33 = 231
- 11 × 21 = 231
How to find the Factors of 231
Divide 231 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 231, so any larger divisor would pair with a smaller one you have already checked.
- 231 ÷ 1 = 231 — factors 1 and 231
- 231 ÷ 2 — remainder 1, not a factor
- 231 ÷ 3 = 77 — factors 3 and 77
- 231 ÷ 4 — remainder 3, not a factor
- 231 ÷ 5 — remainder 1, not a factor
- 231 ÷ 6 — remainder 3, not a factor
- 231 ÷ 7 = 33 — factors 7 and 33
- 231 ÷ 8 — remainder 7, not a factor
- 231 ÷ 9 — remainder 6, not a factor
- 231 ÷ 10 — remainder 1, not a factor
- 231 ÷ 11 = 21 — factors 11 and 21
- 231 ÷ 12 — remainder 3, not a factor
- 231 ÷ 13 — remainder 10, not a factor
- 231 ÷ 14 — remainder 7, not a factor
- 231 ÷ 15 — remainder 6, not a factor
Why 231 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.
231 = 3 × 7 × 11
(1 + 1) × (1 + 1) × (1 + 1) = 8
Step-by-step factorization: Prime factors of 231.
