GCM / GCD Finder For Numbers

This a GCM / GCD Finder For Numbers calculator for students. In mathematics, the greatest common divisor (gcd) of two or more integers, when at least one of them is not zero, is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4.
The GCD is also known as the greatest common factor (gcf), highest common factor (hcf), greatest common measure (gcm), or highest common divisor. This notion can be extended to polynomials and other commutative rings.
