🧮 GCF, LCM & Prime Factors

🧮 GCF, LCM & Prime Factors

Find the greatest common factor, least common multiple and prime factorisation of one or more integers. Enter a single integer to also see whether it is prime and its neighbouring primes. Euclidean algorithm for GCF; trial division up to √n for factors. Integers only, up to 12 digits.
