We do so because if we run the loop from 0 (zero) then we will get ‘Division By Zero Error’. And if we run it only N times then we will not get the number (N) as its own divisor.

Web28 feb. 2024 · 10 has the divisors 1, 2, 5, 10. You initialize divisors with 2 (for 1 and 10). Then mod runs from 2 to 3, and divisors is incremented by one (when mod==2), giving the (incorrect) result 3. Or did I overlook something? – Martin R Feb 20, 2016 at 19:05 You're right. I see it now. The tables below list all of the divisors of the numbers 1 to 1000. A divisor of an integer n is an integer m, for which n/m is again an integer (which is necessarily also a divisor of n). For example, 3 is a divisor of 21, since 21/7 = 3 (and therefore 7 is also a divisor of 21). If m is a divisor of n then so is −m. The tables below only list positive divisors.
