Factor Pairs of 168
A Factor Pair of number 168 is a combination of two factors which can be multiplied together to equal 168.
List of all possible Factor Pairs of 168:
- 1 × 168 = 168
- 2 × 84 = 168
- 3 × 56 = 168
- 4 × 42 = 168
- 6 × 28 = 168
- 7 × 24 = 168
- 8 × 21 = 168
- 12 × 14 = 168
How to find the Factors of 168
Divide 168 by every whole number from 1 up to 12. Each division without a remainder gives a factor and its pair. There is no point going further: 13 × 13 = 169 is already greater than 168, so any larger divisor would pair with a smaller one you have already checked.
- 168 ÷ 1 = 168 — factors 1 and 168
- 168 ÷ 2 = 84 — factors 2 and 84
- 168 ÷ 3 = 56 — factors 3 and 56
- 168 ÷ 4 = 42 — factors 4 and 42
- 168 ÷ 5 — remainder 3, not a factor
- 168 ÷ 6 = 28 — factors 6 and 28
- 168 ÷ 7 = 24 — factors 7 and 24
- 168 ÷ 8 = 21 — factors 8 and 21
- 168 ÷ 9 — remainder 6, not a factor
- 168 ÷ 10 — remainder 8, not a factor
- 168 ÷ 11 — remainder 3, not a factor
- 168 ÷ 12 = 14 — factors 12 and 14
Why 168 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.
168 = 23 × 3 × 7
(3 + 1) × (1 + 1) × (1 + 1) = 16
Step-by-step factorization: Prime factors of 168.
