Tak bym dał w tym kontekście.

The term is used figuratively to refer to the "lowest"—least useful, least advanced, or similar—member of a class or set which is common to things that relate to members of that class. For instance, ASCII characters are the lowest common denominator for computers, in that this set is very limited, but practically every modern computer can interpret binary data into these characters.

The phrase is also used to describe the most basic, least sophisticated level of taste, sensibility, or opinion among a group of people. This is most often used in criticism of art, products or media thought to be aiming itself at such a group, the implied complaint usually being that the subject has been simplified to appeal to a wider audience.
