Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main {
  public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    int a = scanner.nextInt();
    int b = scanner.nextInt();
    int c = scanner.nextInt();
    int count = 0;

    for (int i = a; i <= b; i++) {
      if (c % i == 0) {
        count += 1;
      }
    }

    System.out.println(count);
  }
}
