The Least Common Multiple (or Lowest Common Multiple) of a group of numbers, called the LCM, is the smallest number that's a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that's both a multiple of 16 and a multiple of 20.
common multiples
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
Multiples. Numbers have an infinite number of multiples.
There is an infinite number of common multiples for 21 and 40. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
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).

A single number cannot have common multiples, common multiples can only be shared by two or more numbers.
A single number cannot have a "common multiple" - common multiples are shared by two or more numbers.
A common multiple
All numbers have an infinite amount of multiples.
Multiples. Numbers have an infinite number of multiples.
They are numbers which are not common multiples.
That's called scientific notation.
A common multiple. If it is the lowest possible combination of those numbers, it is called the Least Common Multiple or LCM.
No, all whole numbers have an infinite number of multiples.
