2 x 2 x 2 x 7 = 56
2 x 2 x 3 x 7 = 84
2 x 2 x 7 = 28, the GCF
2 x 2 x 2 x 3 x 7 = 168, the LCM
Check it.
56 x 84 = 4704
28 x 168 = 4704
It checks.

How are gcf LCM and prime factorization related?
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
How do you find GCF and LCM?
To find the GCF and the LCM you have to first at least try to use prime factorization. So use factor trees. Or for the LCM find th least common multiples of the number.
What is the advantage of using prime factorization method in finding LCM?

What is the gcf and the LCM of 18 and 20 using prime factorization?
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
What is the LCM and gcf of 18 and 360?
Product of two numbers a and b = LCM(a,b) x GCF(a,b)...(1)Here, product of 18 and 360 = 6480Now, we shall find GCF of 18 and 360 by using the method of prime factorization.Prime factorization of 18 = 2x3x3Prime factorization of 360 = 2x2x2x3x3x5It is clear from the prime factorization that gcf = 18Now using (1) we can find LCM:LCM(18,360) = Product of 18 and 360/GCF(18,360) = 6480/18 = 360So, LCM and GCF of 18 & 360 is 360 and 18.Also, it is important to note that 360 is divisible by 18 then GCF is 18 and LCM is 360.
