Is 1972 a deficient number?

Here we will explain and calculate if 1972 is a deficient number and its deficiency if applicable.

1972 is a deficient number if the sum of its proper divisors is less than 1972.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 17 + 29 + 34 + 58 + 68 + 116 + 493 + 986 = 1808.

1808 is less than 1972. Therefore, 1972 is a deficient number.
