The greatest common divisor of two whole numbers is the greatest number that divides the others. For example, the greatest common divisor of \(6\) and \(8\) is \(2\), because \(2\) divides both \(6\) and \(8\) and there exists no greater number to do the same. We can use such number to simplify…

Oh wow! That’s the same method I’ve learnt in my Algebra lectures this year :)
