Finding prime factors

Question

#include 
using namespace std;

void whosprime(long long x)
{
    bool imPrime = true;

    for(int i = 1; i <= x; i++)
    {
        for(int z =          


        

Answer 1

Since 600851475143 is out of scope for int as well as single long type wont work here hence here to solve we have to define our own type here with the help of typedef. Now the range of ll is some what around 9,223,372,036,854,775,807.

typedef long long int LL
