Question

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

Answer 1

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.
