Is 1098 a deficient number?

Here we will explain and calculate if 1098 is a deficient number and its deficiency if applicable.

1098 is a deficient number if the sum of its proper divisors is less than 1098.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 18 + 61 + 122 + 183 + 366 + 549 = 1320.

1320 is not less than 1098. Therefore, 1098 is not a deficient number.

The deficiency of 1098 is 1098 minus the sum of its proper divisors. Thus, the deficiency of 1098 is 1098 - 1320 = No Deficiency
