using System.Linq;
using System.Text;

namespace paizaTest
{
    internal class Program
    {
        private static void Main(string[] args)
        {
            var oneLine = Console.ReadLine().Split(' ').Select(int.Parse).ToList();
            var count = 0;

            for (int i = oneLine[0]; i <= oneLine[1]; i++)
            {
                count = oneLine[2] % i == 0 ? ++count : count;
            }
            Console.WriteLine(count.ToString());
        }
    }
