**helper**, Tuesday, January 18, 2011 at 10:46pmmean is the average

add all the numbers to get the sum

divide the sum by the number of numbers you are adding.

33 + 41 + 37 + 27 + 32 = 170

since there are 5 numbers, you divide the sum by 5, to get the mean

170/5 = 34

the mean is 34

LCM

6, 4, 8

LCM is 24

how I was taught

factor each into prime numbers

6 = 2 x 3

4 = 2 x 2

8 = 2 x 2 x 2

write down the most times each factor was used in each factorization

2-was used at most 3 times

3-was used at most 1 time

LCM = (3x2)times (1x3)

LCM = 6x3 = 24

or,

2 x 2 x 2 x 3 = 24

**Ms. Sue**, Tuesday, January 18, 2011 at 10:50pm33 + 41 + 37 + 27 + 32 = 170

170 / 5 = 34

The mean (or average) is 34.

(LCM) for 6,4,and 8?

Which of these numbers is also divisible by 6 and 4?

8, 16, 24, 32, 40

**helper**, Tuesday, January 18, 2011 at 10:53pm4 feet = 4 x 12 in/ft = 48 inches

from above, this should say

write down the most times a factor was used within one factorization
