#include<iostream>
using namespace std;

int main()
{
    int n;
    while (cin >> n)
    {
        int i;
        for (i = 2; i <= n; i++)
        {
            if (n % i == 0)
            {
                n /= i;
                if (n == 1)
                    cout << i << endl;
                else
                    cout << i << "*";
                i = 1;
            }
        }
    }
    return 0;
