How can you use prime factorization to know if two numbers are prime?
A prime number has no factors other than 1 and the number itself. If prime factorization of a number reveals one or more additional prime factors, the number is a composite.
How can you use prime factorization to determine if two numbers are relatively prime?
Once your prime factorization is complete and you discover that there are no numbers in common, the GCF is one and the numbers are declared to be relatively prime.
Can a number greater than 100 have only 1 number in its prime fatorization?
No. Prime numbers (of any size) have only one prime factor, but that's not really a factorization.
Can a composite number have more than one prime factorization?
No, a composite number can't have more than one prime factorization.
How many prime numbers are in the prime factorization of 361?
