My issue

this fails in few test cases.

My code

import java.util.Scanner;

class Codechef {
    public static void main(String[] args) throws java.lang.Exception {
        Scanner sc = new Scanner(System.in);
        int t = sc.nextInt();

        for (int i = 0; i < t; i++) {
            int x = sc.nextInt();
            int y = sc.nextInt();
            int z = sc.nextInt();

            boolean flag = true;

            if (y % z == 0) 
            {
                System.out.println("-1");
            } 
            else 
            {
                int k = x + 1;
                if (k % y != 0) {
                    k = k + y - (k % y);
                while (k % z == 0) {
                    k += y;
                }
                System.out.println(k);
                }
            }
        }

        sc.close();
    }
}
