Is 4002 a deficient number?

Here we will explain and calculate if 4002 is a deficient number and its deficiency if applicable.

4002 is a deficient number if the sum of its proper divisors is less than 4002.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 23 + 29 + 46 + 58 + 69 + 87 + 138 + 174 + 667 + 1334 + 2001 = 4638.

4638 is not less than 4002. Therefore, 4002 is not a deficient number.

The deficiency of 4002 is 4002 minus the sum of its proper divisors. Thus, the deficiency of 4002 is 4002 - 4638 = No Deficiency
