WebOct 15, 2016 · I thought the number itself is also a divisor of itself and therefore added to the sum. Example: "As an example, consider the number 21. Its divisors are 1, 3, 7 and 21, and their sum is 32. Because 32 is less than 2 × 21, the number 21 is deficient. Its deficiency is 2 × 21 − 32 = 10."

WebDec 12, 2014 · When you're looking for integer divisors a, you'll start at 1. You're essentially solving b = n / a and check whether b is an integer. Using the rule of three, this may be rewritten as n = a * b. Due to this, you can assume that once b is smaller than a, you'll only get divisors ´a´, which you've already seen as b before.
