The algorithms that are used the most in practice today [for computing greatest common divisors] are probably the binary algorithm and Euclid's algorithm for smaller numbers, and either Lehmer's algorithm or Lebealean's version of the k-ary GCD algorithm for larger numbers.
State and prove an analogue of the Chinese remainder theorem for the Gaussian integers.

Our subject here is the 'Sturm sequence' of functions defined from a function and its derivative by means of Euclid's algorithm, in order to calculate the number of real roots of a polynomial within a given interval
