Factor Pairs of 2.50 (Rounded to 3) Prime
Decimal Number
You entered 2.50, which is a decimal number. For factor pair calculations, we've rounded to 3, as factor pairs are traditionally calculated for integers only.
All Factor Pairs of 3
Here are all the factor pairs of 3:
Total: 1 factor pair
Prime Number
3 is a prime number, which means it has exactly two factors: 1 and itself. This is why it has only one factor pair.

How to Calculate Factor Pairs of 3
Step-by-Step Process
To find all factor pairs of 3, we need to identify all integers that divide 3 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 3 (v3 ≈ 1.73)
- For each factor found, its corresponding pair is calculated by dividing 3 by that factor
Calculation Example
Let's work through finding the factor pairs of 3:
| Factor Check | Division | Result | Factor Pair |
|---|---|---|---|
| 3 ÷ 1 | 3.00 | Integer result | (1, 3) |
About Decimal Numbers and Factors
Factor pairs are traditionally defined for integers only. For your decimal input 2.50, we've rounded to 3 to perform the calculation.
If you're interested in divisibility properties of decimal numbers, you might want to explore concepts like rational factors or multiplicative inverses in real number fields.

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