The LCM of 2 numbers (x and y) is xy divided by the GCF.
xy = 84*3 = 252.
There are a bunch of factors of 252, so...
252 factors to [2 2 3 3 7]
Give each factor a 3 since GCF=3 is given. You cannot give a two to each or the GCF would be 6. Either one can get the 7.
2*2*3 and 3*7 are the pair (12, 21)
2*2*3*7 and 3 are (84, 3) and also works.■

How do you find the LCM using GCF?
The GCF of two numbers multiplied by their LCM will equal the product of the original numbers. If you know the GCF, divide it into the product of the two. The result will be the LCM. If the GCF of two numbers is 1, the LCM is their product.
Can the GCF of two different numbers is the LCM of the numbers?
No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.
