EXAMPLE
So lets say the numbers you have are 15 and 30.
The factors of 15 and 30 are......
15:1,3,5,15
30: 1,2,3,10,15,30
so the GCF would be 15 because that's the greatest number that goes into 15 and 30.

Great job! I love your links! The only thing I would like to see is more teaching in your explanations - How do you find all of the factors of a number? - for example.
