Is 3 a deficient number?




Here we will explain and calculate if 3 is a deficient number and its deficiency if applicable.

3 is a deficient number if the sum of its proper divisors is less than 3.

The sum of its proper divisors is calculated as follows: 1 = 1.

1 is less than 3. Therefore, 3 is a deficient number.

The deficiency of 3 is 3 minus the sum of its proper divisors. Thus, the deficiency of 3 is 3 - 1 = 2
