Is 1242 a deficient number?

Here we will explain and calculate if 1242 is a deficient number and its deficiency if applicable.

1242 is a deficient number if the sum of its proper divisors is less than 1242.

The sum of its proper divisors is calculated as follows: 1 + 2 + 3 + 6 + 9 + 18 + 23 + 27 + 46 + 54 + 69 + 138 + 207 + 414 + 621 = 1638.

1638 is not less than 1242. Therefore, 1242 is not a deficient number.

The deficiency of 1242 is 1242 minus the sum of its proper divisors. Thus, the deficiency of 1242 is 1242 - 1638 = No Deficiency
