A simple and efficient algorithm for finding the GCD of a pair of univariate polynomials is derived. The process requires only successive subtraction of two monic polynomials. Amazingly, this approach gives the desired GCD for a pair of test polynomials of very high degree, such as ( 𝑥 + 1 ) 1 0 0 0 and its derivative.
