The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy. It was formulated in 1961 by Doctor Frank Drake[1]
The Drake Equation relies on values derived from assumptions. This leads to a value of N being almost anything you want. But it sure does give one some interesting ideas to play with.
Doctor Frank Drake contributed many milestones to the search for extraterrestrial civilizations. He was 92 when he died on September 02, 2022. Definitely a life well lived.
If you would like to know more about Doctor Drake or his equation, here are some articles.

It is so 'guessable' most authorities steer clear of a definitive number. But I did find these:
500 civilizations in the Milky Way Galaxy
https://astrosociety.org/file_downl.....d-06118746d8f1
Drake’s own estimate of his equation is N = L = 10,000 civilizations, which
suggests that the other factors multiply approximately to one (Drake, 2011).
https://arxiv.org/ftp/arxiv/papers/.....1705.07816.pdf
Inserting the above minimum numbers into the equation gives a minimum N of 20 (see: Range of results). Inserting the maximum numbers gives a maximum of 50,000,000. Drake states that given the uncertainties, the original meeting concluded that N ≈ L, and there were probably between 1000 and 100,000,000 planets with civilizations in the Milky Way Galaxy.
