GCF!
What is the GCF of 18 and 36?So, my first tip is to BE NEAT! You must show your work and be legible so your teacher can read it! I start by writing down all the factors of 18 and 36. Try and go in order.... that will make it much easier. Go through each number slowly!18- 1, 2, 3, 6, 9, 18 36- 1, 2, 3, 4, 6, 6, 9, 12, 18, 36So, as you can see there are a few common numbers between 18 and 36! Carefully stare at the factors and circle the common ones. I see 1, 2, 3, 6, and 18 all common. But, the greatest one is 18. So, the GCF of 18 and 36 is 18!Don't get it? Comment your problem and I will try to answer it! But always, always, ALWAYS ask your teacher is this problem is confusing, because MORE THAN LIKELY you WILL see it on your 6th grade Math Midterm!!!!
