Is 266 a deficient number?

Here we will explain and calculate if 266 is a deficient number and its deficiency if applicable.

266 is a deficient number if the sum of its proper divisors is less than 266.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 14 + 19 + 38 + 133 = 214.

214 is less than 266. Therefore, 266 is a deficient number.

The deficiency of 266 is 266 minus the sum of its proper divisors. Thus, the deficiency of 266 is 266 - 214 = 52
