find the LCM for the
following pair of
Pair of numbers.
@ 6 and 9
Answers
LCM = 18
Hope this helps! Thank you!
Step-by-step explanation:
The least common multiple (LCM) of
6
and
9
is
18
and the explanation is down below!
Explanation:
I always take the first 5 multiples of each number and write them down. And if we don't our LCM in there, then I write down the next five multiples! So let's start, shall we?
(First 5) Multiples of
6
:
6
,
12
,
18
,
24
,
30
(First 5) Multiples of
9
:
9
,
18
,
27
,
36
,
45
Now, we have to see if there is any common number in the numbers. If we do, we have to make sure that there isn't any other number lower than that that
6
and
9
go into!

There isn't any number before
18
that
6
and
9
both go into, so
18
is the LCM of
6
and
9
! Now we don't need to write down anymore multiples. :)
