Is 801 a deficient number?

Here we will explain and calculate if 801 is a deficient number and its deficiency if applicable.

801 is a deficient number if the sum of its proper divisors is less than 801.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 89 + 267 = 369.

369 is less than 801. Therefore, 801 is a deficient number.

The deficiency of 801 is 801 minus the sum of its proper divisors. Thus, the deficiency of 801 is 801 - 369 = 432
