2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

#include <iostream>

using namespace std;

int main()

{

    long long j = 20, i, result, counter;

    while (true) {

        counter = 0;

        for (i = 1; i < 21; i++) {

            if (j % i != 0) {

                counter++;

                break;

            }

        }

        if (counter == 0) {

            result = j;

            break;

        }

        j++;

    }

    cout << "Smallest positive number that is evenly divisible by all of the numbers from 1 to 20 is  =  " << result << endl;

    return 0;

}
