Is 258 a deficient number?

Here we will explain and calculate if 258 is a deficient number and its deficiency if applicable.

258 is a deficient number if the sum of its proper divisors is less than 258.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 43 + 86 + 129 = 270.

270 is not less than 258. Therefore, 258 is not a deficient number.

The deficiency of 258 is 258 minus the sum of its proper divisors. Thus, the deficiency of 258 is 258 - 270 = No Deficiency
