确定数的因数 当除数之和不大于该数时，程序将不接受大于 10000 的限制

当我将限制从 100 更改为 1,000,000 时，它不会打印出所有数字，它会停在 5 位数字处，并且不会计算得更高。这是为什么呢？

#include <iostream>
using namespace std;
int main(int argc, char* argv[]) 
{
const int limit = argc > 1 ? atoi(argv[1]) : 100;
const int badness = argc > 2 ? atoi(argv[2]) : 1;

for (int num = 2; num < limit; num++) {
    int total = 1;
    for (int factor = 2; factor * factor <= num; factor++) {
        if (num % factor == 0) {
            total += factor;

            if (factor * factor != num) {
                total += (num / factor);
            }
        }

        }
        if (abs(num - total) <= abs(badness)) {
            cout << num << " " << flush;
        }
    }
}
