How to Calculate Factor Pairs of 4
Step-by-Step Process
To find all factor pairs of 4, we need to identify all integers that divide 4 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 4 (v4 ≈ 2.00)
- For each factor found, its corresponding pair is calculated by dividing 4 by that factor
Calculation Example
Let's work through finding the factor pairs of 4:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 4 ÷ 1 | 4.00 | Integer result | (1, 4) |
| 4 ÷ 2 | 2.00 | Integer result | (2, 2) |

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 4 is deficient because the sum of its proper divisors (3) is less than 4.
All prime numbers are deficient since their only proper divisor is 1.
