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

1 ≤ a, b, c ≤ 10000

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

Solution in C# (judge verdict: Accepted)

using System;

namespace ConsoleApplication15
{
    class Program
    {
        static void Main(string[] args)
        {
            int a, b,c,d;
           
                string[] s = Console.ReadLine().Split(' ');
                a = int.Parse(s[0]);
                b = int.Parse(s[1]);
                c = int.Parse(s[2]);
                d = 0;


                for (int x = a; x <= b; x++)
                {
                    if (c % x == 0)
                    {
                        d++;
                    }
                }

            Console.WriteLine(d);

                }


        }
