Is 2900 a deficient number?

Here we will explain and calculate if 2900 is a deficient number and its deficiency if applicable.

2900 is a deficient number if the sum of its proper divisors is less than 2900.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 20 + 25 + 29 + 50 + 58 + 100 + 116 + 145 + 290 + 580 + 725 + 1450 = 3610.

3610 is not less than 2900. Therefore, 2900 is not a deficient number.

The deficiency of 2900 is 2900 minus the sum of its proper divisors. Thus, the deficiency of 2900 is 2900 - 3610 = No Deficiency
