prime factors

"Prime Factors" is the tenth episode of Star Trek: Voyager.

In number theory, the prime factors of a positive  integer are the prime numbers that divide that integer exactly. The prime factorization of a positive integer is a list of the integer's prime factors, together with their multiplicities; the process of determining these factors is called integer factorization. The fundamental theorem of arithmetic says that every positive integer has a single unique prime factorization.
