Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
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).
The common multiples of 2 and 9 are 18, 36, 54, 72, etc. There is an infinite number of common multiples for 2 and 9. 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).
All of the odd numbers between 11 and 99 inclusive are two digit numbers that are not multiples of 2. There are 45 of them.
The multiples of 12 are 12, 24, 36, 48 and keep on adding 12.The multiples of 16 are 16, 32, 48, 64 and keep on adding 16.If you look at the two of these, you can see there is a least common multiple. A least common multiple is the smallest multiple that are shared by two (or more) numbers. If you list the multiples down, you can see 48 are in both, so 48 is the least common multiple for 12 and 16.

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.
The lowest common factor between two numbers is the multiple apart from 1 that the two numbers share which is the lowest. For example: The numbers 36 and 45. Multiples of 36 are {1,2,3,4,6,9,12,24,36} Multiples of 45 are {1,3,5,9,15,45} It is evident that their shared multiples are 1,3,9. But we exclude 1, therefore 3 is the LCM (or LCF)

A common multiple
A common multiple is used to compare the multiples of two or more numbers - a single number cannot have any common multiples.
This cannot be answered because the common multiples of any two or more numbers are infinite.
This cannot be answered because the common multiples of any two or more numbers are infinite.
A single number cannot have any common multiples - you need two or more numbers to compare.
