1. Lesson 7-1 Factors and Greatest Common Factors
Obj: The student will be able to 1) Write the prime factorization of numbers 2) Find the GCF of monomials HWK: p all, 36(Journal), 63, 64 Vocab: 1) prime factorization 2) greatest common factor

2. Write the prime factorization of each number
Ex 1) Ex 2) Ex 3) 1125

3. Three ways to find GCF
Listing – must list ALL factors
Prime factorization – use lowest power of each common factor
“Box” method – divide until nothing else goes into both numbers, then multiply down the side
(this only works for 2 numbers)

4. Find the GCF of each pair of numbers
Ex 4) 24 and 60

5. Ex 5) 273 and 225

6. Ex 6) 18g² and 27g³

7. Ex 7) 36ab² and 81b Ex 8) 8x and 7v²

8. Ex 9) Adrianne is shopping for a CD storage unit
Ex 9) Adrianne is shopping for a CD storage unit. She has 36 CD’s by pop music artists and 48 CD’s by country music artists. She wants to put the same number of CD’s on each shelf without putting pop music and country music CD’s on the same shelf. If Adrianne puts the greatest possible number of CD’s on each shelf, how many shelves does her storage unit need?
