Is 1984 a deficient number?

Here we will explain and calculate if 1984 is a deficient number and its deficiency if applicable.

1984 is a deficient number if the sum of its proper divisors is less than 1984.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 8 + 16 + 31 + 32 + 62 + 64 + 124 + 248 + 496 + 992 = 2080.

2080 is not less than 1984. Therefore, 1984 is not a deficient number.

The deficiency of 1984 is 1984 minus the sum of its proper divisors. Thus, the deficiency of 1984 is 1984 - 2080 = No Deficiency
