Easy application to calculate the greatest common divisor and least common multiple for two or more numbers at once.

✔ The greatest common divisor (GCD) of two or more integers is the largest positive integer that divides each of the integers.
✔ The least common multiple (LCM) of two or more integers is the smallest positive integer that is divisible by each of the integers.
✔ The greatest common divisor is also known as greatest common factor, highest common divisor, or highest common factor.
✔ The least common multiple is also known as lowest common multiple, or smallest common multiple.
