A number is called first if it is divisible only for itself and for 1; the least common multiple (mcm) of two or more numbers is the least among their common multiples; the maximum common divisor (MCD) of two or more numbers is the largest natural number for which the same numbers can be divided. This application allows you to break down a number into its prime factors (a series of numbers that multiply each other give the original number, and which are all prime numbers) and find the lowest common multiple and the greatest common divisor between two or more numbers entered by the user.
