A factor is a number that can go into a bigger number a even amount of times.
Example:2 is a factor of 8 cause it goes into it 4 times without going over or under .
To find factors of a number you have to test each number to see if it goes in evenly.
Example: factors of 6 I would test 1 it works then 2 it also works 3 is another factor 4 deosnt work nor does 5. 6 goes in evenly too.
When you have two numbers and you need to find the GCF which is the greatest common factor. You would have to list factors of both numbers. Then you would have to find which factors work for both of the numbers. Then you pick the greatest one.
Example:6,12
6=1,2,3,6
12=1,2,3,4,6,12
