Part 1: 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? part 2: give an example of how prime factorization could be used in the real world. part 3: view and comment on the work of at least two other students. explain why you agree or disagree with their ideas.

Part 1:Is it possible for a composite number to have more than one prime factorization?
No.

Is it possible for a number to have no prime factors? Why?
Yes. The number 1 has no prime factors, and 1 is not prime.

Part 2: Give an example of how prime factorization could be used in the real world.
A carpenter needs to add two lengths to cut a piece of wood. One length is 5 1/16 inch, and the other length is 3 3/10 in. By using prime factors of 16 and 10, he can find the least common denominator of 16 and 10, and he can add the lengths together.
