The next step is: 198 = 1 x 171 + 27. For each new step, you take the two rightmost numbers from the previous step.

Then I guess you didn'tlearn the Euclidean Algorithm.*really*

1. Divide the larger number by the smaller.

2. Divide the divisor by the remainder.

3. Repeat step 2 until a zero remainder is achieved.

4. The GCD is the last divisor.

So we have:

Therefore: .
