Solution in JAVA (judge verdict: Accepted)

import java.io.IOException;
import java.util.Scanner;
public class Main {
	public static void main(String[] args) throws IOException{
		Scanner sc = new Scanner(System.in);

		int a = sc.nextInt();
		int b = sc.nextInt();
		int c = sc.nextInt();

		int count = 0;

		for(int i=a;i<=b;i++) {
			if(c%i==0) {
				count++;
			}
		}

		System.out.println(count);

		sc.close();
	}
}
