Is 260 a deficient number?

Here we will explain and calculate if 260 is a deficient number and its deficiency if applicable.

260 is a deficient number if the sum of its proper divisors is less than 260.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 13 + 20 + 26 + 52 + 65 + 130 = 328.

328 is not less than 260. Therefore, 260 is not a deficient number.

The deficiency of 260 is 260 minus the sum of its proper divisors. Thus, the deficiency of 260 is 260 - 328 = No Deficiency
