Is 4278 a deficient number?

Here we will explain and calculate if 4278 is a deficient number and its deficiency if applicable.

4278 is a deficient number if the sum of its proper divisors is less than 4278.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 23 + 31 + 46 + 62 + 69 + 93 + 138 + 186 + 713 + 1426 + 2139 = 4938.

4938 is not less than 4278. Therefore, 4278 is not a deficient number.
