First, to make -5, 6 in simplest form, we need to see what we can divide by. -5 is a prime number (it can’t be divided by any 2 numbers than itself). 6 can be divided by 3 and 2. Since -5 is prime, it remains -5, 6
Second, we need to make -9, -6 in simplest form. So we see what we can divide by again. -9 can be divided by 3 and -6 can be divided by 3. So -9’s and -6’s GCD is -3, 2
