I only know one way sorry. Here it is if you need it. WARNING 6th grader about to give you help!
First find the prime factorization of the numbers (umm... by the way, there is no way to find a common factor with just one number) with the factor trees...
THen when both prime number scentences are in ascending order.
Ex. 93552
2x3x5x5x9
Put both the scentences on top of each other.
Ex.
2x3x3x9
2x3x9x9
Circle and bring down the common factors.
Ex.
(2)x(3)x3x(9)
(2)x(3)x9x(9)
THen, find the product of these numbers.
2x3x9=54!

Kaillif's way is the right way :) I'm in 11th grade and that's still how you do it.
