Question

The LCM of 50, 120, and 225 is 5. true or false?

Answer 1

i would say true

Answer 2

yeah me 2

Answer 3

@NickR You should explain your choice instead of just giving out the answer.

Answer 4

but that requires work :(

Answer 5

225 doesnt go into 10 50 doesnt go into 3
225 doesnt go into 2 so evens are out
if 3 is out so is 6 and 9

Answer 6

and nobody cares about 7 or 8 :P

Answer 7

better @Callisto

Answer 8

Better :)
But doesn't look right though
50 = 2 x 5 x 5
120 = 2 x 2 x 2 x 3 x 5
225 = 15 x 15 = 3 x 3 x 5 x 5

LCM = Least common multiple, isn't it?

Answer 9

yes but needs to apply to all numbers

Answer 10

and i didnt even get a medal :(

Answer 11

That definitely won't be 5 then... Least common multiple would be 2 x 2 x 2 x 3 x 3 x 5 x 5

Answer 12

ah ok http://answers.yahoo.com/question/index?qid=20110315222134AAKpInc

Answer 13

Same as what I've typed. The main problem of the question is to identify what LCM is (definition), and not to confused with HCF (or GCF, you may call).

Answer 14

my bad good catch @Callisto
