Is 143 a deficient number?




Here we will explain and calculate if 143 is a deficient number and its deficiency if applicable.

143 is a deficient number if the sum of its proper divisors is less than 143.

The sum of its proper divisors is calculated as follows: 1 + 11 + 13 = 25.

25 is less than 143. Therefore, 143 is a deficient number.

The deficiency of 143 is 143 minus the sum of its proper divisors. Thus, the deficiency of 143 is 143 - 25 = 118
