Highly Composite Numbers

nextn returns the smallest integer, greater than or equal to n, which can be obtained as a product of powers of the values contained in factors. nextn is intended to be used to find a suitable length to zero-pad the argument of fft to so that the transform is computed quickly. The default value for factors ensures this.
