How to Calculate Factor Pairs of 16

Step-by-Step Process

To find all factor pairs of 16, we need to identify all integers that divide 16 evenly (with no remainder).

Start with the smallest factor, which is always 1
Check each integer from 1 up to the square root of 16 (v16 ≈ 4.00)
For each factor found, its corresponding pair is calculated by dividing 16 by that factor

Calculation Example

Let's work through finding the factor pairs of 16:

Factor Check	Division	Result	Factor Pair
16 ÷ 1	16.00	Integer result	(1, 16)
16 ÷ 2	8.00	Integer result	(2, 8)
16 ÷ 3	5.33	Not a divisor	-
16 ÷ 4	4.00	Integer result	(4, 4)

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 16 is deficient because the sum of its proper divisors (15) is less than 16.

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