Is 1520 a deficient number?

Here we will explain and calculate if 1520 is a deficient number and its deficiency if applicable.

1520 is a deficient number if the sum of its proper divisors is less than 1520.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 16 + 19 + 20 + 38 + 40 + 76 + 80 + 95 + 152 + 190 + 304 + 380 + 760 = 2200.

2200 is not less than 1520. Therefore, 1520 is not a deficient number.

The deficiency of 1520 is 1520 minus the sum of its proper divisors. Thus, the deficiency of 1520 is 1520 - 2200 = No Deficiency
