Is 920 a deficient number?

Here we will explain and calculate if 920 is a deficient number and its deficiency if applicable.

920 is a deficient number if the sum of its proper divisors is less than 920.

The sum of its proper divisors is calculated as follows: 1 + 2 + 4 + 5 + 8 + 10 + 20 + 23 + 40 + 46 + 92 + 115 + 184 + 230 + 460 = 1240.

1240 is not less than 920. Therefore, 920 is not a deficient number.

The deficiency of 920 is 920 minus the sum of its proper divisors. Thus, the deficiency of 920 is 920 - 1240 = No Deficiency
