Is 2106 a deficient number?

Here we will explain and calculate if 2106 is a deficient number and its deficiency if applicable.

2106 is a deficient number if the sum of its proper divisors is less than 2106.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 13 + 18 + 26 + 27 + 39 + 54 + 78 + 81 + 117 + 162 + 234 + 351 + 702 + 1053 = 2976.

2976 is not less than 2106. Therefore, 2106 is not a deficient number.

The deficiency of 2106 is 2106 minus the sum of its proper divisors. Thus, the deficiency of 2106 is 2106 - 2976 = No Deficiency
