Solution in JAVA (judge verdict: Accepted)

import java.util.*;

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