Is it possible for a composite number to have more then o e prime factorization? and is it possible for a number to have no prime factorization

1. No, because every prime factor can not be prime factorized again. It could have more factorizations, but at least one of the factors would be a composite number which is the product of at least two of the prime factors.

2. Prime numbers and 1 do not have their prime factorization.
