Is 345 a deficient number?

Here we will explain and calculate if 345 is a deficient number and its deficiency if applicable.

345 is a deficient number if the sum of its proper divisors is less than 345.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 15 + 23 + 69 + 115 = 231.

231 is less than 345. Therefore, 345 is a deficient number.

The deficiency of 345 is 345 minus the sum of its proper divisors. Thus, the deficiency of 345 is 345 - 231 = 114
