Is 4428 a deficient number?

Here we will explain and calculate if 4428 is a deficient number and its deficiency if applicable.

4428 is a deficient number if the sum of its proper divisors is less than 4428.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 18 + 27 + 36 + 41 + 54 + 82 + 108 + 123 + 164 + 246 + 369 + 492 + 738 + 1107 + 1476 + 2214 = 7332.

7332 is not less than 4428. Therefore, 4428 is not a deficient number.

The deficiency of 4428 is 4428 minus the sum of its proper divisors. Thus, the deficiency of 4428 is 4428 - 7332 = No Deficiency
