6.7A Prime Factorization

prime number ? a whole

number that has exactly two factors, 1 and itself.

composite number ? a number

greater than 1 with more than two factors.

factors - numbers that you

exponential notation ? used for writing repeated multiplication

more efficiently through the use of bases and exponents.

multiply together to get another number.

factor tree ? an organized diagram used for listing out pairs factor strings ? repeated

of factors of a number until reaching the prime factors of a

multiplication by the same factor

number.

Prime and Composite Numbers ? the prime numbers are circled, the composite numbers are not circled

My teacher's learning goals for me are that I will be able to:

Build a factor tree to calculate the prime factors of any composite number.

Generate equivalent expressions o using factor strings.

o using exponential notation. Calculate the composite value when

given a factor string or exponential notation.

I will master the learning goals for Prime Factorization with

at least _______ mastery by: 1) Asking questions when I'm not sure of something and answering questions when I know the answer.

When the composite number that is being factored is negative, you must first factor out the negative 1 (put a triangle around it). In doing this, the number that you are now calculating the prime factorization for is positive.
