Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Multiples of 210 will all be common multiples of 30 and 42 and can be found by multiplying 210 by successive counting numbers.
210 x 1 = 210
210 x 2 = 420
210 x 3 = 630 and so on.

What is the least common multiple of 11 and 17?
The Least Common Multiple (LCM) for 11 17 is 187. All you do is find the multiples of 11 and on the 17th one you'll get 187 and for 17 on the 11th multiple will be 187 and that their Least Common Multiple.
Least common multiple of 9 and 12?
To find the LCM of 2+ multiples, you have to write the multiples of it out first.So, in this case, it's 12 and 9.12: 12,24,36,48,etc..9: 9,18,27,36, etc...so the LCM is 36.Recommend please! :D
What are the Common multiples of the numbers 45 and 8?
common multiples of 45 are 9 and 5 and common multiples of 8 are 4 and 8. This person doesn't know what common multiple is. (up) New author: You have to find if it is the LCM or the MCM, Least common multiple is 360 New author: MCM can't exist, it is no point finding it. Every MCM of multiple numbers are always infinity
What is the least common multiple of 4?
You need two numbers to find a least common multiple. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more given whole numbers. The C in LCM stands for common and in general we only talk about common multiples of two or more numbers.You need at least two numbers to find an LCM.
What is the least common multiple of 108?
You need at least to numbers to find a least common multiple.
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 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.
What are the common multiples of 8?
You can't find the Common Multiple of only one number. You need at least two numbers to find the common multiples.
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 is a least multiple?
All sets of numbers have common multiples. It is sometimes advantageous to find the smallest of these. This is known as the least common multiple or LCM.
What is the least common multiple of 13?
You need at least two numbers to find a least common multiple.
What are the common multiples of 12?
You can't find the Common Multiple of only one number. You need at least two numbers to find a common multiple.
