Méthode	Description
gcd ( int x ) : int	Method that calculates the Greatest Common Divisor (GCD) of several positive integer numbers.
gcd ( int x1, int x2 ) : int	Method that calculates the Greatest Common Divisor (GCD) of two positive integer numbers.
lcm ( int x ) : int	Method that calculates the Least Common Multiple (LCM) of several positive integer numbers.
lcm ( int x1, int x2 ) : int	Method that calculates the Least Common Multiple (LCM) of two strictly positive integer numbers.
log2 ( int x ) : int	Method that calculates the floor of the log, base 2, of 'x'. The calculation is performed in integer arithmetic, therefore, it is exact.
