It is often useful to write an integer n > 1, as a product of primes. The Fundamental Theorem of Arithmetic states that this is always possible, and moreover, that this factorization is unique. In this talk, I will illustrate what uniqueness means in this context, and give an elementary example of a number system in which unique factorization fails to hold. Finally, I will mention the role that uniqueness of factorization played in 350 years of attempts to prove Fermat's Last Theorem.
