Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

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

		}
	}
