3. Find the GCF of 20 and 24

4. Find the GCF of25 , 125, and 200

5. Find the GCF! 30 53

6. Relatively PrimeGCF = 1

7. Find the GCf of 9, 36, 60

8. 3

9. Find the LCM of 18 and 30

10. 90

11. Find the LCM! 18, 20, 24

12. LCM = 360

13. Find the LCM 9 and 16

14. Relatively PrimeLCM = 144

15. N = 23, Commutative Property of +

16. N = 3, Distributive Property

17. Use variables a,b and c to define the Associative Property of Multiplication.

18. a(bc) = (ab)c

19. a (b + c) = ab + ac

20. Find the GCF and LCM of 12 and 20

21. GCF = 4 LCM = 60

22. Find the GCF and LCM of 9, 12, and 25

23. ** GCF = 1 ** LCM = 900

24. GCF or LCM ? You decide. Two bikers are riding a circular path. The first rider completes a round in 12 minutes. The second rider completes a round in 18 minutes. If they both started at the same place and time and go in the same direction, after how many minutes will they meet again at the starting point?
