that not my question . i want to know how to do the other problem as well on the meant for the following number?
33,41,37,27,32,?

• 5th math -

mean 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

• 5th math -

33 + 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

• 5th math -

4 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
