Is 828 a deficient number?

Here we will explain and calculate if 828 is a deficient number and its deficiency if applicable.

828 is a deficient number if the sum of its proper divisors is less than 828.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 18 + 23 + 36 + 46 + 69 + 92 + 138 + 207 + 276 + 414 = 1356.

1356 is not less than 828. Therefore, 828 is not a deficient number.

The deficiency of 828 is 828 minus the sum of its proper divisors. Thus, the deficiency of 828 is 828 - 1356 = No Deficiency
