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 sum = 0;
		int a = scan.nextInt(); //????????§???????????\???
		int b = scan.nextInt(); //????????§???????????\???
		int c = scan.nextInt(); //????????§???????????\???
		for (int x = a; x <= b; x++){
			if(c % x == 0){
				sum++;
			}
		}
		System.out.println(sum);

	}
