Is 1275 a deficient number?

Here we will explain and calculate if 1275 is a deficient number and its deficiency if applicable.

1275 is a deficient number if the sum of its proper divisors is less than 1275.

The sum of its proper divisors is calculated as follows: 1 + 3 + 5 + 15 + 17 + 25 + 51 + 75 + 85 + 255 + 425 = 957.

957 is less than 1275. Therefore, 1275 is a deficient number.
