Solution in JAVA (judge verdict: Accepted)

import java.util.*;

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