Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
	public static void main(String[]args){
		//????????£???
		Scanner sc = new  Scanner(System.in);
		//a?????\??????
		int a = sc.nextInt();
		//b?????\??????
		int b = sc.nextInt();
		//c?????\??????
		int c = sc.nextInt();
		//????????????
		int count =0;
		//?´???°?????°????????????
		for(int i= a; i <= b; i++){
			if(c % i <=0){
				count++;
			}else{

			}
		}
		System.out.println(count);
	}
