Is 465 a deficient number?

Here we will explain and calculate if 465 is a deficient number and its deficiency if applicable.

465 is a deficient number if the sum of its proper divisors is less than 465.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 15 + 31 + 93 + 155 = 303.

303 is less than 465. Therefore, 465 is a deficient number.

The deficiency of 465 is 465 minus the sum of its proper divisors. Thus, the deficiency of 465 is 465 - 303 = 162
