Can you always find the least common multiple of two numbers by multiplying them together.why or why not?

You can always find a common multiple of two numbers by multiplying them together; it will not always be the least common multiple. As one counterexample, if one of the numbers is a multiple of the other, the first number is the LCM of the two.

9 x 3 = 27

The LCM of 9 and 3 is 9.

4 x 6 = 24

The LCM of 4 and 6 is 12.
