Method: Integer#gcdlcm

Defined in:
lib/framework/rational18.rb,
lib/framework/rationalME.rb

#gcdlcm(other) ⇒ Object

Returns the GCD and the LCM (see #gcd and #lcm) of the two arguments (self and other). This is more efficient than calculating them separately.

Example:

6.gcdlcm 9     # -> [3, 18]
