A simple way to think about it is that "or" is based on "plus" which gives you smaller results than "times" just as "GCD" will tend to be smaller than "LCM".
More importantly, what is the GCD versus the LCM for boolean arguments? The result tables are the same as "or" and "and", respectively. This gives you consistent results whether you think of zero and one as numbers or as boolean values.
