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? 2.give and example of how prime factorization could be used in the real world

Composite number is defined as a number that can be divided by numbers aside from 1 and by itself.

Prime number are numbers that only has a factors of 1 and itself.

It is very possible for a composite number to have more than one prime factorization. But, it is not possible for a number to not have a prime factor. 

When you factorize a number, you break it down into its most basic factors and these basic factors are all prime numbers.

Prime factorization is basically breaking down numbers to its most basic factors. It can be used in everyday living especially when we deal with numerical transactions like money and values.
