You need at least two numbers to compare multiples.
All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. On the list of common multiples, one number is the smallest. This is the least common multiple.

Short answer: There is none. There is not a least common multiple of a single number, such as 54, because there cannot be any form of common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there is not a least common multiple. The lowest common multiple of 54 depends upon the other number(s) with which it has COMMON multiples and is one of the multiples of 54. The common multiples of 54 depends upon the other numbers with which 54 has COMMON multiples and are the multiples of the least common multiples between 54 and the other number(s).
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
You need at least two numbers to find something in common.
The least common multiple of the numbers 7 and 11 is 77.
The least common multiples of the numbers 3,4 and 6 would be 12. This is a math problem.
All nonzero numbers have multiples. Any two numbers will have an infinite number of multiples in common. The smallest of these is known as the least common multiple, or LCM.
To have an LCM, you need at least 2 numbers.
There is not a least common multiple of a single number, such as 6x15y, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.
