Least common multiple is defined for integers, not for rational numbers. You can find the least common multiple of the denominators, though - they are integers, and this calculation is useful for adding or subtracting fractions.

The LCM of 2 numbers can be one of those numbers when the large of the 2 numbers is 2 times the smaller one of those numbers. For example the LCM of 2 and 4 is 4. For example the LCM of 5 and 10 is 10.

No, this will find a common multiple, but not always the least. For example, 2 and 4 have a least common multiple of 4 but if you multiply them you get 8. In fact, the LCM will only be the product of two numbers if the numbers have no commo...

You multiply the two numbers and then you divide your answer by two. Or you could divide both numbers by two and then see which answer is smaller. the smaller one is your answer.
