If we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + R and B≠0 then GCD (A,B) = GCD (B,R) where Q is an integer, R is an integer between 0 and B-1. The first two properties let us find the GCD if either number is 0.

http://pkirs.utep.edu/cis3355/Tutorials/chapter2/IntegerStorage.htm WebTo negate a signed 8-bit value (ranging from -128 to +127), toggle all the bits, then add 1. A error has occurred if a carry is generated — the initial value was out of range (a negated -128 can’t produce +128). Negating a 16-bit value is similar. Flip the bits of both bytes. Add 1 to the LSB. If a carry is generated, add 1 to the MSB.
