1 Mr. Coon’s Math Class

2  The answer to a multiplication problem. 6 X 6 = 36

3 7 X 8 = 56

4 8 X 9 = 72

5  The product of a whole number multiplied times any other whole number. Some multiples of 6 6, 12, 18, 24, 30, 36, 42

6 5, 10, 15, 20, 25, 30, 35

7 7, 14, 21, 28, 35, 42, 49

8 4, 8, 12, 16, 20, 24, 28

9 9, 18, 27, 36, 45, 54, 63

10  A number that is a multiple of two or more numbers. Some multiples of 3 & 6 6, 12, 18, 24, 30, 36, 42

11 8, 16, 24, 32, 40, 48, 56

12 12, 24, 36, 48, 56, 60

13 21, 42, 63

14 10, 20, 30, 40, 50, 60

15  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

16 8 = 8, 16, 24, 32, 40, 48 3 = 3, 6, 9, 12, 15, 21, 24

17 8 = 8, 16, 24, 32, 40, 48 4 = 4, 8, 12, 16, 20, 24

18 8 = 8, 16, 24, 32, 40, 48 6 = 6, 12, 18, 24, 30, 36

19 10 = 10, 20, 30, 40, 50, 4 = 4, 8, 12, 16, 20, 24

20 9 = 9, 18, 27, 36, 45, 54 3 = 3, 6, 9, 12, 15, 21,

21  Find the multiples of each denominator. 1 = 5, 10, 15, 20, 25, 30 1 = 10, 20, 30, 40,

22  Compare the lists of multiples. Circle the common multiples between the two lists. 1 5 = 5, 10, 15, 20, 25, = 10, 20, 30, 40, 50 +

23  Use the lowest common multiple as the denominator. 1 5 = 5, 10, 15,20,25, = 10, 20, 30, 40, 50 +

24  This number is also called the least common denominator. 1 5 = 5, 10, 15,20,25, = 10, 20, 30, 40, 50 +

25 1 2 = 2, 4, 6, 8, 10, = 8, 16, 24, 32, 40 +

26 1 10 = 10, 20, 30, 40, 1 8 = 8, 16, 24, 32, 40 +

27 1 10 = 10, 20, 30, 40, 1 4 = 4, 8, 12, 16, 20, +

28 1 2 = 2, 4, 6, 8, 10, 1 4 = 4, 8, 12, 16, 20, +

29 1 2 = 2, 4, 6, 8, 10, = 12, 24, 36, 48 +

30 1 3 = 3, 6, 9, 12, = 4, 8, 12, 16, 20, +

31 1 3 = 3, 6, 9, 12, = 5, 10, 15, 20, 25, +

32 1 3 = 3, 6, 9, 12, = 9, 18, 27, 36, 45, +

33 Check to see if the smaller denominator divides evenly into the larger denominator. If it does, use the larger denominator for your LCD or LCM. 3 will divide evenly into 9, so 9 is your LCD or LCM.

34 Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 4, so 4 is your LCD or LCM.

35 Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 10, so 10 is your LCD or LCM.

36 Using the shortcut, what is the LCD or LCM? 2 will divide evenly into 12, so 12 is your LCD or LCM.

37 Using the shortcut, what is the LCD or LCM? 4 will divide evenly into 8, so 8 is your LCD or LCM.

38 Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 6, so 6 is your LCD or LCM.

39 Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 12, so 12 is your LCD or LCM.

40 Using the shortcut, what is the LCD or LCM? 3 will divide evenly into 15, so 15 is your LCD or LCM.

41 Using the shortcut, what is the LCD or LCM? 3 will not divide evenly into 8, so find the least common multiple.
