Is 470 a deficient number?

Here we will explain and calculate if 470 is a deficient number and its deficiency if applicable.

470 is a deficient number if the sum of its proper divisors is less than 470.

The sum of its proper divisors is calculated as follows: 1 + 2 + 5 + 10 + 47 + 94 + 235 = 394.

394 is less than 470. Therefore, 470 is a deficient number.

The deficiency of 470 is 470 minus the sum of its proper divisors. Thus, the deficiency of 470 is 470 - 394 = 76
