How to Calculate Factor Pairs of 423
Step-by-Step Process
To find all factor pairs of 423, we need to identify all integers that divide 423 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 423 (v423 ≈ 20.57)
- For each factor found, its corresponding pair is calculated by dividing 423 by that factor

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 423 is deficient because the sum of its proper divisors (201) is less than 423.
All prime numbers are deficient since their only proper divisor is 1.
