Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.

What do common multiples multiples and least common multiples have in common?
They are all multiples.
What are the common multiples of 4 and 5?
The common multiples of 4 and 5 are 20, 40, 60, 80,100 and so onGet the least common multiple of the two. All other common multiples are multiples of this least common multiple.Any multiple of 20.
What do you call multiples that are shared by two or more numbers?
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
What is the least common multiple of 54?
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).
What is the least common multiples of 9 between 70 and 105?
You need at least two numbers to find an LCM. The multiples of 9 between 70 and 105 are 72, 81, 90 and 99.
How do you find the most common multiple?
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
What are the least common multiples of 147?
You can not find the least common multiple of just one number. You can find the multiples of 147 but have nothing to compare it to to find the "least" first 6 multiples of 147 - 147, 294, 441, 588, 735, 882

They are all multiples.
Find the least common multiples of 12?
You need at least two numbers to find an LCM.
What are the first two common multiples of 5 3 and 8?
All common multiples of a set of numbers are multiples of the least common multiple. Therefore:* Use any standard procedure to find the LEAST common multiple. * Multiply that by 1, by 2, by 3, etc. to find additional common multiples.
What are the two digit common multiples of 2 8 and 10?
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.
