8. LEAST COMMON MULTIPLE The smallest common multiple of a set of two or more numbers. 6 = 6, 12, 18, 24, 30, 36 5 = 5, 10, 15, 20, 25, 30

9. WHAT IS THE LEAST COMMON MULTIPLE OF 3 & 8 8 = 8, 16, 24, 32, 40, 48 3 = 3, 6, 9, 12, 15, 21, 24

10. WHAT IS THE LEAST COMMON MULTIPLE OF 4 & 8 8 = 8, 16, 24, 32, 40, 48 4 = 4, 8, 12, 16, 20, 24

11. PRACTICE FIND LCM FOR THE FOLLOWING 2 5

12. WHAT IS THE LCD OR LEAST COMMON DENOMINATOR Find the multiples of each denominator. 1 = 5, 10, 15, 20, 25, 30 1 = 10, 20, 30, 40, 50 + 5 10

13. WHAT IS THE LCD OR LEAST COMMON DENOMINATOR Compare the lists of multiples. Circle the common multiples between the two lists. 1 5 = 5, 10, 15, 20, 25, 30 1 10 = 10, 20, 30, 40, 50 +

14. WHAT IS THE LCD OR LEAST COMMON DENOMINATOR Use the lowest common multiple as the denominator. 1 5 = 5, 10, 15,20,25,30 1 10 = 10, 20, 30, 40, 50 +

15. WHAT IS THE LCD OR LEAST COMMON DENOMINATOR This number is also called the least common denominator. 1 5 = 5, 10, 15,20,25,30 1 10 = 10, 20, 30, 40, 50 +

16. FIND THE LEAST COMMON DENOMINATOR OR LEAST COMMON MULTIPLE 1 2 = 2, 4, 6, 8, 10, 12 1 8 = 8, 16, 24, 32, 40 +

17. FIND THE LEAST COMMON DENOMINATOR OR LCD 1 10 = 10, 20, 30, 40, 1 8 = 8, 16, 24, 32, 40 +

18. FIND THE LEAST COMMON DENOMINATOR 1 10 = 10, 20, 30, 40, 1 4 = 4, 8, 12, 16, 20, +

19. What is the LCM used for? The LCM is used to find common denominators so that fractions may be easily compared, added, or subtracted. > GIANT ONE

20. The Giant One is used to find equivalent fractions. It is used to reduce or simplify fractions. The giant one works because of the Identity Property. copyright©amberpasillas2010

21. To compare fractions sometimes we use inequality symbols rather than an equal sign. Means larger or greater than Means smaller or less than Means equal to > < = Large # Small # The hungry alligator eats the larger number.
