2 and 3 because they're the lowest two numbers you can get between 1 and 40.
Factors go into numbers, numbers go into multiples.
All numbers have common multiples.
what two numbers between 50 and 60 are both multiples of the same number. what factor do they have in common?
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.
All pairs have the same same number of multiples: [countably] infinitely many.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
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).
The product of the GCF and LCM of two numbers will equal the product of the two numbers.
If both of your numbers divide into them evenly with no remainder, they are common multiples.
You need at least two numbers to find something in common between them.
