Is 2006 a deficient number?

Here we will explain and calculate if 2006 is a deficient number and its deficiency if applicable.

2006 is a deficient number if the sum of its proper divisors is less than 2006.

The sum of its proper divisors is calculated as follows: 1 + 2 + 17 + 34 + 59 + 118 + 1003 = 1234.

1234 is less than 2006. Therefore, 2006 is a deficient number.

The deficiency of 2006 is 2006 minus the sum of its proper divisors. Thus, the deficiency of 2006 is 2006 - 1234 = 772
