Question

please help

Answer 1

1. 4?, 2. 3,
3. 4
i think thats what you're after?

Answer 2

1. Can you list all the factors of 12?
And 16?

Answer 3

Not quite Georgia, but you're close. For GCF, you're trying to find the biggest number that both of terms can be divisible by.

Answer 4

Yes.
And what about for 2?

Answer 5

Yes. And remember the x's. they are also part of the GCF

Answer 6

Ok, go back to #1. The GCF is just 4 because 12 and 16x can be divisible by 4 and that's the greatest number they can be divisible by. It cannot be 4x because 12 does not have an x term in it.

Answer 7

Just look at the numbers and the x's separately. What is the greatest factor of the two numbers. Then, how many x's do these two terms share.

Answer 8

Yup. Now your 1. Is wrong. It's suppose to be just 4.
You can't put 4x because they don't have an x in COMMON
Only 12x has a x, 16 does not.

Lets break it up 2.
Name all the factors of 18x^2
And 15x^5

Answer 9

No. I have no idea what you're doing with the 2.
But I could help you list just the factors of 18.
1,18,2,9,3,6
Does this make sense?
If so, can you try to list the factors of 15?

Answer 10

Yes.
So
18: 1,2,3,6,9,18
15: 1,3,5,15

Look at this. What's the largest factor they have in common?

Answer 11

YES.
And now lets look at the variable.
One has x^2 and the other x^5.
When finding the greatest common factor of the variable, you want to find the smallest one. So which is smaller, x^2 or x^5

Answer 12

Yes. Correct.
So put them together.
The GCF for 2. Is 3x^2.
Does this make sense now? Can you try to do 3?

Answer 13

No. GcF of 12 and 40.
List all the factors of 12.
Then 40.
And do the same thing, find the largest factor they have in common

Answer 14

Yes. Now lets look at the variables.
Lets start with a.
One has a^5 and the other has a^5. Which is smaller?

Answer 15

Yes. They're the same, so a^5
Now lets look at the b.
One is b and the other is b^5. Which is smaller

Answer 16

Ok. Now put them all together.
What is the GCF of 12a^5b and 40a^5b^5?

Answer 17

No. There are no x in any of the terms.
RECAP
What did we say the GCF of:
A) 12 and40?
B) a^5 and a^5?
C) b and b^5?

Answer 18

No. That's just partA.
What about B and C

Answer 19

Yes. Now put A,B,C together to make a term

Answer 20

Correct. That is your GCF

Answer 21

Thanks so much for helping!

Answer 22

No problem
