Prime numbers are only divisable by one and itself.
Composite nimbers are divisable by more than two factors.
Prim Factorization= A composite number written as the product of its prim factors.
An easy way to find the (GCF) is to use the latter method. All you do is divid a prime factor by two until you get to a prime number. Then you take the same numbers on each latter and multiply them together to get the (GCF).
You can also use a vendiagram. You put one of the prime factors on one saide and the other on the other side. Then u use the latter method to find numbers that both prime factors have in common. Then you multiply the numbers that are the same to get the (GCF).
