Today in class we learned about prime factorization. We learned a new method called the birthday cake method. To do this method you start out with the number you want and than you find the lowest prime factor that goes into that number. you than put the answer on the top of the original number and do this again. Than you take all of the numbers on the side and add them up. We also learned the definition of prime and composite numbers today. Prime Number-is a number that can only be divided by 1 and its self. An example of this would be 2,3,5,7, ect. The cool thing about 2 is that it is the only even prime number. Composite Number- is when the number has more factors than just one and its self. Examples of this would be 28,27,24 ect.
