The LCM of a set of integers is the smallest positive integer which can be divided evenly by each number in the set. The LCM of the set is the same however it is calculated.
LCM- using 14 12 and 10 is 420
That's a lot of extra work for this problem but here goes. 3 is already prime so it doesn't really have a factor tree or prime factorization. The prime factorization of 4 is 2 x 2 which looks like this in a factor tree.42,23 and 4 have no common prime factors, so the LCM is their product, 12
it is a method in mathematics that helps to find out LCM
I factor because the problem I'm solving calls for it. It's the fastest and easiest way to solve for the GCF or LCM.
you have to use a factor tree

Since 6 and 7 share no common factor other than 1, the LCM is their product, 42.
The factor tree finds the prime factorization. The prime factorization finds the LCM. Example: 30 and 42 Factor them. 30 15,2 5,3,2 42 21,2 7,3,2 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

32=2x16=2x2x8=2x2x2x4=2x2x2x2x2 45=3x15=3x3x5 LCM=(2x2x2x2x2)x(3x3x5) =1440
