How to Calculate Factor Pairs of 7
Step-by-Step Process
To find all factor pairs of 7, we need to identify all integers that divide 7 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 7 (v7 ≈ 2.65)
- For each factor found, its corresponding pair is calculated by dividing 7 by that factor
Calculation Example
Let's work through finding the factor pairs of 7:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 7 ÷ 1 | 7.00 | Integer result | (1, 7) |
| 7 ÷ 2 | 3.50 | Not a divisor | - |

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 7 is deficient because the sum of its proper divisors (1) is less than 7.
All prime numbers are deficient since their only proper divisor is 1.
