How to Calculate Factor Pairs of 9
Step-by-Step Process
To find all factor pairs of 9, we need to identify all integers that divide 9 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 9 (v9 ≈ 3.00)
- For each factor found, its corresponding pair is calculated by dividing 9 by that factor
Calculation Example
Let's work through finding the factor pairs of 9:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 9 ÷ 1 | 9.00 | Integer result | (1, 9) |
| 9 ÷ 2 | 4.50 | Not a divisor | - |
| 9 ÷ 3 | 3.00 | Integer result | (3, 3) |

More About Deficient Numbers
Deficient Numbers
A deficient number is a positive integer for which the sum of its proper divisors is less than the number itself. The number 9 is deficient because the sum of its proper divisors (4) is less than 9.
All prime numbers are deficient since their only proper divisor is 1.
