Slide 3

MULTIPLES The word MULTIPLE looks a lot like MULTIPLY Multiplying make things large, so Multiples are the large numbers that are formed by multiplying the original by counting numbers. Another to say it that a multiple is the product of factors! Ex. Multiples of 6 6x2=12 so 12 is the next multiple Therefore, 6,12,18 are the first 3 multiples of 6 6x1=6 so 6 is the first multiple 6x3=18 so 18 is the next multiple

Slide 4

4 x 1 = 4 4 x 2 = 8 4 x 3 = 12 4 x 4 = 16 4 x 5 = 20 4 x 6 = 24 Counting Numbers So, the first six multiples of 4 are 4, 8, 12, 16, 20, 24, 28 EXAMPLE: LIST THE MULTIPLES OF 4: Write this example down just as you see it.

Slide 5

13 x 1 =13 13 x 2 = 26 13 x 3 = 39 13 x 4 = 52 13 x 5 = 65 13, 26, 39, 52, 65 WHAT ARE THE FIRST FIVE MULTIPLES OF 13? Write this example down just as you see it.

Slide 6

LOWEST COMMON MULTIPLE Once you have the lists of a few multiples for the two numbers You can pick the smallest or lowest number that is in both (common) lists That number is the Lowest Common Multiple for those two numbers Examples. 8: 8,16,24,32 12:12,24,36 16: 16,32,48,60 24: 24,48,72 24 is the LCM 48 is the LCM Make sure you get the steps written down!!!

Slide 7

4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 9: 9, 18, 27, 36, 45, 36 is the LCM of 4 and 9 FIND THE LCM OF 4 AND 9 Write this example down just as you see it.

Slide 8

Well, thats all for today. If there is time left in the period, practice in the math text book on page 103. Tomorrow we will pick up with prime and composite numbers. Please study your notes from today and your homework assignment is on Pearsonsuccessnet titled Factors. Do your best as this is your very first practice math grade!
