Is 1925 a deficient number?

Here we will explain and calculate if 1925 is a deficient number and its deficiency if applicable.

1925 is a deficient number if the sum of its proper divisors is less than 1925.

The sum of its proper divisors is calculated as follows: 1 + 5 + 7 + 11 + 25 + 35 + 55 + 77 + 175 + 275 + 385 = 1051.

1051 is less than 1925. Therefore, 1925 is a deficient number.

The deficiency of 1925 is 1925 minus the sum of its proper divisors. Thus, the deficiency of 1925 is 1925 - 1051 = 874
