Question

Could someone please help me understand this?
Find the least common multiple of

Answer 1

\[3x^{2}\] , \[12^{y}\] and \[10x^{3}y^{3}\]

Answer 2

when u said 12y was it supposed to be y to a power? or just y?

Answer 3

woops sorry yeah its should be 12y

Answer 4

hmm if im remembering correctly would it be 3 for 3x^2 and 12y? and 2y for 12y and 10x^3y^3

Answer 5

okay..

Answer 6

so how'd you get that?

Answer 7

A method to find them is to factor what is given. Then you mupliply back what is the union of them.

Answer 8

okay, thanks guys!

Answer 9

no problem meh loe ^.^

Answer 10

\(\color{red}{3\cdot x\cdot x}\) I need all 3 of these.
\(\color{blue}{2\cdot 2\cdot} \color{red}{3}\color{blue}{\cdot y}\) I already have a 3.
\(\color{green}{5}\cdot \color{blue}{2} \color{green}{\cdot x}\color{red}{\cdot x\cdot x} \color{green}{\cdot y\cdot y}\color{blue}{\cdot y}\) I already have a 2, 2 xes, an a y.

\(\color{red}{3\cdot x\cdot x}\color{blue}{\cdot 2\cdot 2\cdot y}\color{green}{\cdot 5\cdot x\cdot y\cdot y}\)

\(2\cdot 2\cdot 3\cdot 5\cdot x\cdot x\cdot x\cdot y\cdot y\cdot y\)

\(60x^3y^3\)

Answer 11

ohh okay thank you so much :D

Answer 12

If I remember.... Let me see if I can fid a reference to it.

Answer 13

okay

Answer 15

Thank you!!

Answer 16

Their comment on highest power makes sense. Easier than what I did.

Answer 17

My tri-color thing took a while to make. Hehe. So that is why the late detail. But I think it is worth it. Shows how I got the different parts of:
\(\color{red}{3\cdot x\cdot x}\color{blue}{\cdot 2\cdot 2\cdot y}\color{green}{\cdot 5\cdot x\cdot y\cdot y}\)

Answer 18

so i just looked at that website and now that i think about it my answer is completely wrong sorry :(

Answer 19

its okay Alley you tried :D And thank you @e.mccormick :D

Answer 20

@tester97 Well, you got the start of it. You have to factor it to find the LCM. That is probably what you are remembering. How to start it. Now you can remember how to finish it too!

Answer 21

nahhhhhh mick i rather not cos i have something else to do right now i just came here cos katt said she needed help but i failed her........

Answer 22

its okayyy Alley at least you tried! :D

Answer 23

@tester97 /poke /poke
Not that hard to remember this. Highest powers from each and then multiply out the union of the prime factors of the constant terms.

Answer 24

but but but mick......i dont wanna do anymore math right now im doing chemistry ugh...and btw i dont like to be poked :P

Answer 25

Hmmm... well... union might not be 100% correct... eliminates some duplicates. Unique prime factors is more proper to say.

Answer 26

Chemistry uses math!

Answer 27

lol i know but not too much

Answer 28

Answer 29

are u trying to give me a heart attack? im too pretty to die!

Answer 30

Linear Algebra gets no love....
