Is 1988 a deficient number?

Here we will explain and calculate if 1988 is a deficient number and its deficiency if applicable.

1988 is a deficient number if the sum of its proper divisors is less than 1988.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 7 + 14 + 28 + 71 + 142 + 284 + 497 + 994 = 2044.

2044 is not less than 1988. Therefore, 1988 is not a deficient number.

The deficiency of 1988 is 1988 minus the sum of its proper divisors. Thus, the deficiency of 1988 is 1988 - 2044 = No Deficiency
