How to Calculate Factor Pairs of 2

Step-by-Step Process

To find all factor pairs of 2, we need to identify all integers that divide 2 evenly (with no remainder).

Start with the smallest factor, which is always 1
Check each integer from 1 up to the square root of 2 (v2 ≈ 1.41)
For each factor found, its corresponding pair is calculated by dividing 2 by that factor

Calculation Example

Let's work through finding the factor pairs of 2:

Factor Check	Division	Result	Factor Pair

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 2 is deficient because the sum of its proper divisors (1) is less than 2.

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