What is the least common multiple of 9?

Answer 1

Common with what? Least Common Multiple (not multipleS) is a single number that you can determine only if you are given two numbers. In other words, it is a function with two inputs and one output, therefore it makes no sense to ask "what is the least common multiple of 9?"

As an example, the least common multiple of 9 and 6 is 18, because 18 is the smallest number which is a multiple of both 9 and 6.

Answer 2

To find the least common multiple, you have to have at least 2 numbers.
