Is 3381 a deficient number?

Here we will explain and calculate if 3381 is a deficient number and its deficiency if applicable.

3381 is a deficient number if the sum of its proper divisors is less than 3381.

The sum of its proper divisors is calculated as follows: 1 + 3 + 7 + 21 + 23 + 49 + 69 + 147 + 161 + 483 + 1127 = 2091.

2091 is less than 3381. Therefore, 3381 is a deficient number.

The deficiency of 3381 is 3381 minus the sum of its proper divisors. Thus, the deficiency of 3381 is 3381 - 2091 = 1290
