Application to calculate the Greatest Common Factor (GCF) and the Least Common Multiple (LCM) of several numbers (from 2 to 10 numbers). Each number can have ten digits.

The app gives you the prime factors of the numbers the user has introduced and the prime factors of the GCF and the LCM (of those numbers).
It is similar to the way students calculate the Greatest common factor and the Least common multiple of several numbers. You get the prime factors of the numbers
and then you choose the common factors with smaller exponents (GCF) or you choose common and uncommon factors with bigger exponents (LCM).

The app is also very useful to get prime factorization of several numbers at the same time.
