Solution in JAVA (judge verdict: Accepted)

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