        int p, q, i, g = 0, x;
        // p & q - To store the two positive numbers
        // x - To store the LCM number
        // g - To store the GCD

        System.out.println ("-----Enter the two positive integer numbers-----");
        p = in.nextInt();
        q = in.nextInt();

        for (i = 1; i <= p && i <= q; ++i) {
            if (p % i == 0 && q % i == 0) {
