GCF!

Its time to get started the first thing you have to do is factor out the GCF. The GCF is the largest number that both numbers can easily be divided into. For example...........

1. 100 and 10................ The GCF is 10. That one was really easy but it shows you that the GCF can not be larger than the smallest number.

2. 24 and 32................ The GCF is 8. As you can see both can be divided by 8 but that's the highest number.

Still need help on factoring. Now to factor in an equation its pretty basic. It is the same thing with an x for example...........

3. 6x+12 The GCF is 6 so its transformed into 6(x+2).

4. 2x 2 +2x-4 The GCF is 2 so it becomes 2(x 2 +x-2)
