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).

one
A single number cannot have a "common multiple" - common multiples are shared by two or more numbers.
Multiples of 983 include 983, 1966, 2949 and 3932. For them to be common, they need to be compared to another set of multiples.
A common multiple
Multiples. Numbers have an infinite number of 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.
It's called a number. Every non-zero integer has two or more multiples.
Common denominators. These are called "common multiples". For example, multiples of 4 are: 4,8,12,16,20,24 ... . Multiples of 6 are: 6,12,18,24,30,36 ... . The numbers on both lists are the common multiples and they include: 12,24,36, ... . Specifically, the smallest number in any such list of common multiples (12 in this example) is known as the Least (or Lowest) Common Multiple or LCM.
