Is 2457 a deficient number?

Here we will explain and calculate if 2457 is a deficient number and its deficiency if applicable.

2457 is a deficient number if the sum of its proper divisors is less than 2457.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 9 + 13 + 21 + 27 + 39 + 63 + 91 + 117 + 189 + 273 + 351 + 819 = 2023.
