What are the Factors of 220?
Answer
Factors of 220:
1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
(number 220 has 12 factors)
Factor Pairs of 220
A Factor Pair of number 220 is a combination of two factors which can be multiplied together to equal 220.
List of all possible Factor Pairs of 220:
- 1 × 220 = 220
- 2 × 110 = 220
- 4 × 55 = 220
- 5 × 44 = 220
- 10 × 22 = 220
- 11 × 20 = 220
How to find the Factors of 220
Divide 220 by every whole number from 1 up to 14. Each division without a remainder gives a factor and its pair. There is no point going further: 15 × 15 = 225 is already greater than 220, so any larger divisor would pair with a smaller one you have already checked.
- 220 ÷ 1 = 220 — factors 1 and 220
- 220 ÷ 2 = 110 — factors 2 and 110
- 220 ÷ 3 — remainder 1, not a factor
- 220 ÷ 4 = 55 — factors 4 and 55
- 220 ÷ 5 = 44 — factors 5 and 44
- 220 ÷ 6 — remainder 4, not a factor
- 220 ÷ 7 — remainder 3, not a factor
- 220 ÷ 8 — remainder 4, not a factor
- 220 ÷ 9 — remainder 4, not a factor
- 220 ÷ 10 = 22 — factors 10 and 22
- 220 ÷ 11 = 20 — factors 11 and 20
- 220 ÷ 12 — remainder 4, not a factor
- 220 ÷ 13 — remainder 12, not a factor
- 220 ÷ 14 — remainder 10, not a factor
Why 220 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.
220 = 22 × 5 × 11
(2 + 1) × (1 + 1) × (1 + 1) = 12
Step-by-step factorization: Prime factors of 220.
