Best Answer

By using prime factorization. Example: 30 and 42

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

What is the LCM of 28 and 24?

To figure out the LCM you should first find out how your number should be written using it's prime factors.Eg. 28=2x2x7 as all these numbers are prime#24=2x2x2x3The LCM will then be the product of these numbers you have just found(note. for 28 you have 2x2 and for 24 you have 2x2x2. It is not necessary to use 2x2x2x2x2. all you need to have is 2x2x2 as this is the largest amount of that number used to make up 24 or 28.)eg. LCM = 2x2x2x3x7=168Hopefully that helps and is not too confusing!
