How to Calculate Factor Pairs of 388
Step-by-Step Process
To find all factor pairs of 388, we need to identify all integers that divide 388 evenly (with no remainder).
- Start with the smallest factor, which is always 1
- Check each integer from 1 up to the square root of 388 (v388 ≈ 19.70)
- For each factor found, its corresponding pair is calculated by dividing 388 by that factor
Calculation Example

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 388 is deficient because the sum of its proper divisors (298) is less than 388.
All prime numbers are deficient since their only proper divisor is 1.
