Remember !

A natural number d is called the greatest common divisor (gcd) of the numbers a and b if there is a number c another common divisor of a and b then c | d.

Algorithm for calculating gdc:

1. The numbers are divided into prime factors

2. The common prime factors are chosen only once from each having the smallest exponent and will be multiplied between them.
