If 1 was considered as prime, then prime factorization of positive integers would not be unique.
   For example, 6 could be written as (2)(3) (a product of 2 prime factors), or as (2)(3)(1) (a product of 3 prime factors).

The Fundamental Theorem of the Algebra has nothing to do with prime numbers.


The fundamental theorem of arithmetic states that "Every whole number greater than 1 can be written as a product of prime numbers in exactly one way, except for the order of the factors." My question asks me to show how this theorem would be affected if 1 was defined to be a prime number(although it's not). Sorry if I was unclear the first time and thanks for the effort! Have a nice day! :)
