How to Calculate Factor Pairs of 27
Step-by-Step Process
To find all factor pairs of 27, we need to identify all integers that divide 27 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 27 (v27 ≈ 5.20)
- For each factor found, its corresponding pair is calculated by dividing 27 by that factor
Calculation Example
Let's work through finding the factor pairs of 27:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 27 ÷ 1 | 27.00 | Integer result | (1, 27) |
| 27 ÷ 2 | 13.50 | Not a divisor | - |
| 27 ÷ 3 | 9.00 | Integer result | (3, 9) |
| 27 ÷ 4 | 6.75 | Not a divisor | - |
| 27 ÷ 5 | 5.40 | 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 27 is deficient because the sum of its proper divisors (13) is less than 27.
All prime numbers are deficient since their only proper divisor is 1.
