  1. Prime or Composite?Factors or Multiples? • Objective: I can differentiate between prime and composite numbers. I can differentiate between factors and multiples. Created by Chris Garrison Sycamore 5th grade

  2. What are... Composite Numbers? Prime Numbers? have more than two factors have “exactly twofactors” 1 and itself

  3. Factors are small Multiples are BIG!

  4. Get Ready! Let’s practice what we know!

  5. Is this number prime or composite? Show all work and carefully find all the factors! 16 Composite!

  6. Is this number prime or composite? Show all work and carefully find all the factors! 24 Composite!

  7. Is this number prime or composite? Show all work and carefully find all the factors! 17 Prime!

  8. Is this number prime or composite? Show all work and carefully find all the factors! 64 Composite!

  9. a. 2, 3, 5, 7, 9, 13, b. 1, 4, 5, 7, 11, 13, c. 3, 5, 7, 13, 17, 19 Test for success! Think smarter not harder! Example Which of following are all prime numbers? X X X X Tip Eliminate composite numbers first. Then double check remaining numbers to make sure they are all prime.

  10. Is this number a factor or a multiple of 9? Prove it! 27 Multiple

  11. Is this number a factor or a multiple of 36? Prove it! 12 Factor

  12. Is this number a factor or amultiple of 18? Prove it! 6 Factor

  13. Is this number a factor or amultiple of 7? Prove it! 49 Multiple

  14. Is this number a factor or amultiple of 24? Prove it! 8 Factor

  15. Is this number a factor or a multiple of 12? Prove it! 96 Multiple

  16. Greatest Common Factor (GCF) The greatest factor two numbers share. 1. List the factors for each number. 2. Circle common factors. 3. Choose the greatest factor. 30: 1, 2, 3, 5, 6, 10, 15, 30 GCF = 15 15: 1, 2, 3, 5, 15

  17. Least Common Multiple Least multiple that more than one number share. 1. List the first 5 multiples of each number. 2. Choose the smallest multiple they both share. LCM: 6 2: 2, 4, 6, 8, 10 3: 3, 6, 9, 12, 15

  18. 1, 2, 3, 4, 6, 8, 12, 24 Test for success! Think smarter not harder! Example Which of following are the factors of 24? a. 1, 2, 3, 4, 6, 8, 12, 24 b. 1, 4, 6, 5, 8, 12, 24, X X X c. 2, 3, 6, 8, 12, 24, 48 Double check all factors with... Tips Eliminate any answer choice that includes a multiple. Factor Rainbow

  19. Closure Turn to your shoulder partner and tell them the difference between a factorandmultiple. Now tell them the difference between primeandcomposite number.
