How to Calculate Factor Pairs of 13

Step-by-Step Process

To find all factor pairs of 13, we need to identify all integers that divide 13 evenly (with no remainder).

Start with the smallest factor, which is always 1
Check each integer from 1 up to the square root of 13 (v13 ≈ 3.61)
For each factor found, its corresponding pair is calculated by dividing 13 by that factor

Calculation Example

Let's work through finding the factor pairs of 13:

Factor Check	Division	Result	Factor Pair
13 ÷ 1	13.00	Integer result	(1, 13)
13 ÷ 2	6.50	Not a divisor	-
13 ÷ 3	4.33	Not a divisor	-

About Decimal Numbers and Factors

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 13 is deficient because the sum of its proper divisors (1) is less than 13.

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