Is 1035 a deficient number?

Here we will explain and calculate if 1035 is a deficient number and its deficiency if applicable.

1035 is a deficient number if the sum of its proper divisors is less than 1035.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 9 + 15 + 23 + 45 + 69 + 115 + 207 + 345 = 837.

837 is less than 1035. Therefore, 1035 is a deficient number.
