a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class PG{
    static void Main(string[] args){
        int[] nums=Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
        int a,b,c,n;
        n=0;
        a=nums[0];
        b=nums[1];
        c=nums[2];
        for(int i=a;i<=b;i++){
            if(c%i==0){
                n++;
            }
        }
        Console.WriteLine(n);
    }
}
