WebDivisors of an integer in Python. We will first take user input (say N) of the number we want to find divisors. Then we will run a loop from 1 to (N+1). 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.

WebDec 7, 2013 · 1. As far as efficiency is concerned you should first generate a list of divisors 12-> {2,2,3} then group them -> { {2,2}, {3}} then apply product of sets (see here ). This way you never check for divisors above n^ (0.5) and make your search for divisors very efficient. Share. Improve this answer. WebIt is straightforward to check that 1 to 6 are no divisors of the expression, since they are factors of $12!$, $6!$ and $12!6!$. Further, 7 is a divisior of both $12!$ and $12!6!$.

WebWell, every whole number is divisible by 1. This is a whole number, so 1 is a factor at the low end. 1 is a factor. That's its actual smallest factor, and its largest factor is 120. You can't have something larger than 120 dividing evenly into 120. 121 will not go into 120. So the largest factor on our factors list is going to be 120.
