It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You cannot have an LCM for only one number!
LCM of 18 34 and 6 is 306.
The LCM is: 180
You cannot find the LCM of one number. There must be two numbers to compare, because the C means common.
You need at least two numbers to find the LCM
It is: 54
90
You need at least two numbers to find an LCM. If that's 6 and 9, the LCM is 18.
You need at least two numbers to find an LCM. If that's 38 and 18, the LCM is 342.
