(a) Find the GCF of 18 and 8

(b) use the GCF to factor 18-8

18 - 8 = blank x (blank - blank)

A) 2- The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 8 are 1, 2, 4, and 8. This means that the greatest factor they have in common is 2.

b) 2*(9-4). You divide both 18 and 8 by their GCF. You can check this- 18-8 is 10 and 2*5 is 10. (I got the 5 from 9-4.)
