Input

Three integers a, b and c are given in a line separated by a single space.

Output

Print the number of divisors in a line.

Constraints

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>
  
  int main(void){
            int a,b,tem;
          while(1){
            scanf("%d %d",&a,&b);
            if( a==0 && b==0 )
                  break;
            if( a>b){
                  tem =a;
                    a =b;
                    b =tem;
                 }
              printf("%d %d\n",a,b);
                }
             return 0;
              }
