Gcf = 2
LCM = 132
Express the numbers in prime factorisation in power form: 12 = 22 x 31 27 = 33 For gcf multiply together the lowest power of the common primes: gcf of 12 and 27 = 31 = 3 For LCM multiply together the highest power of all the primes (across the numbers): LCM of 12 and 27 = 22 x 33 = 108
22 is a factor of 110. 110 is a multiple of 22. That means that 22 is the GCF and 110 is the LCM of those two numbers.
You need at least two numbers to find a GCF or LCM, as they they are relationships between multiple numbers.
This is confusingly written. I think that someone wants you to learn the fact that the product of two numbers is equal to the product of their LCM and GCF. Example: 6 and 8 GCF = 2 LCM = 24 6 x 8 = 48 2 x 24 = 48 So 22 x 23 = 506 If the GCF is 2, then the LCM is 253. But the GCF of 22 and 23 isn't 2. And 253 isn't a multiple of 22 or 23. And 22 and 23 wouldn't be the factors of two numbers. This may not have been copied correctly.

The LCM of these numbers is 4620. LCM is Least Common Multiple.
The Least Common Multiple (LCM) for 11 33 22 is 66.
The GCF is 3.
The LCM is 132.
The GCF of 12 15 and 22 is 1.
Since 22 is a factor of 110, it is automatically the GCF of this problem.
They are: 286 and 1 respectively
