A googol in mathematics is the number 10 raised to the power 100. The term is said to have been coined in 1920 by nineyearold Milton Sirotta, nephew of American mathematician Edward Kasner. 1 googol is roughly equal to 70! and its only prime factors are 2 and 5.
The search engine Google's PR department has the following to say on the company's name: "Google is a play on the word googol [and] Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web."
P.S. 1 googol = 10^100 = 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.
