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.he 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.
There are many ways to find if a polynomial is prime. First, a prime polynomial is one that cannot be factored with real numbers. For example, the polynomial x^2-1 is not prime, because we can factor it to be (x+1)(x-1). However, the similar polynomial x^2+1 is in fact prime because we cannot factor it with the real numbers. I like to use some simple steps when determining whether or not a polynomial is prime. First, like fernando said, i look for simple things to factor out, like an x or 2.
