I have a problem with this code at the time of running. help me please.

Question

using System;
class ProjectEuler3{
public static void Main(){

long limit = 600851475143;
int mf = 0;
for (int p=1;p<10;p++){
if(limit%p==0){
mf = p;
}
else{continue;}
}
Console.WriteLine(mf);
}
}

tells me that you are trying to divide by 0, what should I do?

Answer 1

Thank you so much.

Answer 2

No problem 👌
And good luck! 👍

Answer 3

Are you sure you initialized <p> in the loop by 1? division by zero error shouldn't be raised unless <p> was initialized by zero.

Answer 4

yes, the value of "p" is inside the loop, and I need to enter a value of 12 digits but I can not use "int" I have to use "long" but I do not know how, how would you implement it?

Answer 5

Can you describe the program please? I'm not understanding what you are trying to do here ...

Answer 6

I need to find the largest prime factor of 600851475143.

Answer 7

I hope this helps you somehow
