1 Prime Factorization: Objective: To identify prime and composite numbers. To write the prime factorization of numbers Vocabulary Prime Number: A number greater than 1 that has only two factors (1 and the number itself) Examples: 5: because 5 and 1 are its only factors 17: because 17 and 1 are its only factors Composite Number: A whole number greater than one that has more than two factors. Examples: 6: because it has four factors 1, 2, 3, 6 9: because it has three factors 1, 3, 9

2 0 and 1 are neither prime or composite Prime Factorization: A number written as a product of factors that are all prime numbers. Factor Tree: A useful tool used to find prime factorization. Example: Make a factor tree for the number All three factor trees have three 2’s and a 5 The prime factorization of 40 is
