Is 430 a deficient number?

Here we will explain and calculate if 430 is a deficient number and its deficiency if applicable.

430 is a deficient number if the sum of its proper divisors is less than 430.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 43 + 86 + 215 = 362.

362 is less than 430. Therefore, 430 is a deficient number.

The deficiency of 430 is 430 minus the sum of its proper divisors. Thus, the deficiency of 430 is 430 - 362 = 68
