Re: gcd 0 0 = 0

, Here an integer a divides an integer b if there is an integer c such that b = c*a. Note that if you regard an integer a to be greater than another integer b if b divides a then the gcd of two intgerers may also be regarded as the greatest common divisor of a and b. Regards, Marc van Dongen
