Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace ConsoleApplication32
{
    class Program
    {  
      static void Main()
      {
		  var a = Console.ReadLine().Split().Select(int.Parse).ToArray();
		  int c =0;
		  for (int b=a[0];b<a[1]+1;b++)
		  {
			  if(a[2]%b==0)
			  c++;
		  }
		  Console.WriteLine(c);
		  		}
	 }
