Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime factors? Why?

Give an example of how prime factorization could be used in the real world.

7 answers

1. No. After the first prime factorization, no further factoring can be done.

2. Yes. Prime numbers(2, 3, 5, 7) have no prime factors; because they have already gone through "Prime factorization".
