Is 2142 a deficient number?

Here we will explain and calculate if 2142 is a deficient number and its deficiency if applicable.

2142 is a deficient number if the sum of its proper divisors is less than 2142.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 7 + 9 + 14 + 17 + 18 + 21 + 34 + 42 + 51 + 63 + 102 + 119 + 126 + 153 + 238 + 306 + 357 + 714 + 1071 = 3474.

3474 is not less than 2142. Therefore, 2142 is not a deficient number.

The deficiency of 2142 is 2142 minus the sum of its proper divisors. Thus, the deficiency of 2142 is 2142 - 3474 = No Deficiency
