Omar says that the least common multiple of 9 and 6 is 54. Which is true about Omar's statement?

A.54 is not a common multiple of 6 and 9

B.54 is the least common multiple.

C.54 is a common multiple, but not the least common multiple.

D.54 is also the greatest common factor.

Hey there!

Let's pull out the multiples of each number and see which ones fall in line first.

9,18

6,12,18

The LCM is 18. Therefore, answer B and D are incorrect. A is incorrect because 9 * 6 is 54. Therefore, the answer is C.

I hope this helps!
