Is 378 a deficient number?

Here we will explain and calculate if 378 is a deficient number and its deficiency if applicable.

378 is a deficient number if the sum of its proper divisors is less than 378.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 7 + 9 + 14 + 18 + 21 + 27 + 42 + 54 + 63 + 126 + 189 = 582.

582 is not less than 378. Therefore, 378 is not a deficient number.

The deficiency of 378 is 378 minus the sum of its proper divisors. Thus, the deficiency of 378 is 378 - 582 = No Deficiency
