WebWe show that an iteration of the Borwein-Borwein quartic algorithm for p is equivalent to two iterations of the Gauss-Legendre quadratic algorithm for p, in the sense that they produce exactly the same sequence of approximations to p … WebThe best algorithm that is known is to express the factorial as a product of prime powers. One can quickly determine the primes as well as the right power for each prime using a sieve approach. Computing each power can be done efficiently using repeated squaring, and then the factors are multiplied together. how do you make cream of tartar
