How to Calculate Factor Pairs of 8
Step-by-Step Process
To find all factor pairs of 8, we need to identify all integers that divide 8 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 8 (v8 ≈ 2.83)
- For each factor found, its corresponding pair is calculated by dividing 8 by that factor
Calculation Example
Let's work through finding the factor pairs of 8:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 8 ÷ 1 | 8.00 | Integer result | (1, 8) |
| 8 ÷ 2 | 4.00 | Integer result | (2, 4) |

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 8 is deficient because the sum of its proper divisors (7) is less than 8.
All prime numbers are deficient since their only proper divisor is 1.
