Is 2871 a deficient number?

Here we will explain and calculate if 2871 is a deficient number and its deficiency if applicable.

2871 is a deficient number if the sum of its proper divisors is less than 2871.

The sum of its proper divisors is calculated as follows: 1 + 3 + 9 + 11 + 29 + 33 + 87 + 99 + 261 + 319 + 957 = 1809.

1809 is less than 2871. Therefore, 2871 is a deficient number.
