largest prime factor of ​N. Bluestein’s algorithm solves this problem by allowing us to evaluate a Fourier transform of size N​ using Fourier transforms of a different size ​K, with the only constraint that K be no smaller than 2N-1. For instance, for N = 7919​ (which is a prime number), ​it can be
