Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main{
    public static void main(String[] args){
	Scanner sc=new Scanner(System.in);
	int a = sc.nextInt();
	int b = sc.nextInt();
	int c = sc.nextInt();
        int ct=0;
        for(int i=a;i<=b;i++){
            if(c%i==0){
                ct++;
            }
        }
        System.out.println(ct);
    }
}
