Is 3940 a deficient number?

Here we will explain and calculate if 3940 is a deficient number and its deficiency if applicable.

3940 is a deficient number if the sum of its proper divisors is less than 3940.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 10 + 20 + 197 + 394 + 788 + 985 + 1970 = 4376.

4376 is not less than 3940. Therefore, 3940 is not a deficient number.

The deficiency of 3940 is 3940 minus the sum of its proper divisors. Thus, the deficiency of 3940 is 3940 - 4376 = No Deficiency
