(number 490 has 12 factors)
Factor Pairs of 490
A Factor Pair of number 490 is a combination of two factors which can be multiplied together to equal 490.
List of all possible Factor Pairs of 490:
- 1 × 490 = 490
- 2 × 245 = 490
- 5 × 98 = 490
- 7 × 70 = 490
- 10 × 49 = 490
- 14 × 35 = 490
How to find the Factors of 490
Divide 490 by every whole number from 1 up to 22. Each division without a remainder gives a factor and its pair. There is no point going further: 23 × 23 = 529 is already greater than 490, so any larger divisor would pair with a smaller one you have already checked.
- 490 ÷ 1 = 490 — factors 1 and 490
- 490 ÷ 2 = 245 — factors 2 and 245
- 490 ÷ 3 — remainder 1, not a factor
- 490 ÷ 4 — remainder 2, not a factor
- 490 ÷ 5 = 98 — factors 5 and 98
- 490 ÷ 6 — remainder 4, not a factor
- 490 ÷ 7 = 70 — factors 7 and 70
- 490 ÷ 8 — remainder 2, not a factor
- 490 ÷ 9 — remainder 4, not a factor
- 490 ÷ 10 = 49 — factors 10 and 49
- 490 ÷ 11 — remainder 6, not a factor
- 490 ÷ 12 — remainder 10, not a factor
- 490 ÷ 13 — remainder 9, not a factor
- 490 ÷ 14 = 35 — factors 14 and 35
- 490 ÷ 15 — remainder 10, not a factor
- 490 ÷ 16 — remainder 10, not a factor
- 490 ÷ 17 — remainder 14, not a factor
- 490 ÷ 18 — remainder 4, not a factor
- 490 ÷ 19 — remainder 15, not a factor
- 490 ÷ 20 — remainder 10, not a factor
- 490 ÷ 21 — remainder 7, not a factor
- 490 ÷ 22 — remainder 6, not a factor
Why 490 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.
490 = 2 × 5 × 72
(1 + 1) × (1 + 1) × (2 + 1) = 12
Step-by-step factorization: Prime factors of 490.
