The number 42 is, in "The Hitchhiker's Guide to the Galaxy", calculated by an enormous supercomputer named Deep Thought over a period of 7.5 million years.

The Ultimate Question "What do you get when you multiply six by nine" is found by Arthur Dent and Ford Prefect in the second book of the series, "The Restaurant at the End of the Universe".
