Is 3825 a deficient number?

Here we will explain and calculate if 3825 is a deficient number and its deficiency if applicable.

3825 is a deficient number if the sum of its proper divisors is less than 3825.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 9 + 15 + 17 + 25 + 45 + 51 + 75 + 85 + 153 + 225 + 255 + 425 + 765 + 1275 = 3429.

3429 is less than 3825. Therefore, 3825 is a deficient number.

The deficiency of 3825 is 3825 minus the sum of its proper divisors. Thus, the deficiency of 3825 is 3825 - 3429 = 396
