WebNot surprisingly, the algorithm bears Euclid's name. If b a then gcd (a, b) = b. This is indeed so because no number (b, in particular) may have a divisor greater than the number itself (I am talking here of non-negative integers.) If a = bt + r, for integers t and r, then gcd (a, b) = gcd (b, r). Indeed, every common divisor of a and b also ...
