How to Calculate Factor Pairs of 404

Step-by-Step Process

To find all factor pairs of 404, we need to identify all integers that divide 404 evenly (with no remainder).

Start with the smallest factor, which is always 1
Check each integer from 1 up to the square root of 404 (v404 ≈ 20.10)
For each factor found, its corresponding pair is calculated by dividing 404 by that factor

Calculation Example

Let's work through finding the factor pairs of 404:

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 404 is deficient because the sum of its proper divisors (310) is less than 404.

All prime numbers are deficient since their only proper divisor is 1.
