Is 506 a deficient number?

Here we will explain and calculate if 506 is a deficient number and its deficiency if applicable.

506 is a deficient number if the sum of its proper divisors is less than 506.

The sum of its proper divisors is calculated as follows: 1 + 2 + 11 + 22 + 23 + 46 + 253 = 358.

358 is less than 506. Therefore, 506 is a deficient number.

The deficiency of 506 is 506 minus the sum of its proper divisors. Thus, the deficiency of 506 is 506 - 358 = 148
