Is 805 a deficient number?

Here we will explain and calculate if 805 is a deficient number and its deficiency if applicable.

805 is a deficient number if the sum of its proper divisors is less than 805.

The sum of its proper divisors is calculated as follows: 1 + 5 + 7 + 23 + 35 + 115 + 161 = 347.

347 is less than 805. Therefore, 805 is a deficient number.

The deficiency of 805 is 805 minus the sum of its proper divisors. Thus, the deficiency of 805 is 805 - 347 = 458
