Is 1284 a deficient number?

Here we will explain and calculate if 1284 is a deficient number and its deficiency if applicable.

1284 is a deficient number if the sum of its proper divisors is less than 1284.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 4 + 6 + 12 + 107 + 214 + 321 + 428 + 642 = 1740.

1740 is not less than 1284. Therefore, 1284 is not a deficient number.

The deficiency of 1284 is 1284 minus the sum of its proper divisors. Thus, the deficiency of 1284 is 1284 - 1740 = No Deficiency
