I found an article that mentioned that instead of iterating from 1 upto n, one can reduce the overall running time by iterating from 1 upto sqrt(n), and if suppose 1<=k<=sqrt(n), and k is a divisor of the number n, then another divisor will be n/k.

WebThere are propertieswhich allow one to recognize certain divisors of a number from the number's digits. Those properties can be used as "math tricks" to quickly spot some divisors of a number. For example, if the last digit is even (0, 2, 4, 6 or 8), then 2 is a divisor. If the last digit is 0 or 5, then 5 is a divisor. http://www.positiveintegers.org/150

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.
