Its ancient name, dating back to ancient India, is the pulverizer. And we will see what that does in a moment. So the theorem that is the culmination that we're aiming for is that the GCD of two numbers is an integer linear combination of the two numbers. That is, the GCD of a and b is simply sa plus tb, where s and t are integers. And what the ...
