Question

Find the least common multiple of these two expressions.

16u^3 w^2 y^6 and 24 u^5 w ^8

Answer 1

You pulled out the correct variables. You can simplify the numbers a bit more.

Answer 2

Oh, wait, least common multiple. I was thinking GCF. Don't remember what LCM is. :/

Answer 3

i cannot remember that either . .:/

Answer 4

To find LCM of 16 and 24
Find multiples of both 16 and 24 until they are the same
16: 16,32,48,64,...
24:24,48,72,...

So what multiple do they have in common?

Answer 5

48

Answer 6

so it would be 48u^3w^2 ?

Answer 7

Correct.
Do the same with the variable
u^3 and u^5
So find LCM of 3 and 5

Answer 8

i mean U^3

Answer 9

the answer is corretc im runnig out of time

Answer 10

Oops nvm. Variables is the one with the highest power.
So it'll be
48u^5 w^8 y^6

Answer 11

oh i see but why we have to include Y if is not common i guess

Answer 12

It's not common.
You're looking or the least common multiple
Since one of them is y^6 and the other one doesn't, or you can call it y^0
The greater one would be y^6

With variables it's the one with the bigger exponent
For example,

c^100 f^2 p^5. And f^9 p^4
The LCM would be
c^100 f^9 p^5
Does this make sense?
