Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

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