This is a very well optimized version of my prime factorization algorithm in Python. The link to my old versions can be found here.
# reduces the parameter n into a product of only prime numbers # and returns a list of those prime number factors def primeFactorize(n): primeFactors =  primeFactor = 0 i = 2 while i <= n / i: if n % i == 0: primeFactor = i primeFactors.append(i) n /= i else: i += 1 if primeFactor < n: primeFactors.append(int(n)) else: primeFactors.append(primeFactor) return primeFactors # example print (primeFactorize(13195)) # [5, 7, 13, 29]DOWNLOAD
