Is 406 a deficient number?

Here we will explain and calculate if 406 is a deficient number and its deficiency if applicable.

406 is a deficient number if the sum of its proper divisors is less than 406.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 14 + 29 + 58 + 203 = 314.

314 is less than 406. Therefore, 406 is a deficient number.

The deficiency of 406 is 406 minus the sum of its proper divisors. Thus, the deficiency of 406 is 406 - 314 = 92
