Is 2940 a deficient number?

Here we will explain and calculate if 2940 is a deficient number and its deficiency if applicable.

2940 is a deficient number if the sum of its proper divisors is less than 2940.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 10 + 12 + 14 + 15 + 20 + 21 + 28 + 30 + 35 + 42 + 49 + 60 + 70 + 84 + 98 + 105 + 140 + 147 + 196 + 210 + 245 + 294 + 420 + 490 + 588 + 735 + 980 + 1470 = 6636.

6636 is not less than 2940. Therefore, 2940 is not a deficient number.

The deficiency of 2940 is 2940 minus the sum of its proper divisors. Thus, the deficiency of 2940 is 2940 - 6636 = No Deficiency
