Additional functions include finding prime\nfactors and Ruth-Aaron pairs, finding next and previous prime\nnumbers in the series, finding or estimating the nth prime,\nestimating the number of primes less than or equal to an\narbitrary number, computing primorials, prime k-tuples (e.g.,\ntwin primes), finding the greatest common divisor and smallest\n(least) common multiple, testing whether two numbers are\ncoprime, and computing Euler's totient function. Most functions\nare vectorized for speed and convenience.", "License": "MIT + file LICENSE", "URL": "https://github.com/ironholds/primes", "BugReports": "https://github.com/ironholds/primes/issues",
