Is 1274 a deficient number?

Here we will explain and calculate if 1274 is a deficient number and its deficiency if applicable.

1274 is a deficient number if the sum of its proper divisors is less than 1274.

The sum of its proper divisors is calculated as follows: 1 + 2 + 7 + 13 + 14 + 26 + 49 + 91 + 98 + 182 + 637 = 1120.

1120 is less than 1274. Therefore, 1274 is a deficient number.

The deficiency of 1274 is 1274 minus the sum of its proper divisors. Thus, the deficiency of 1274 is 1274 - 1120 = 154
