what is the GCF of?

Question

hwat is the GCF of 16,24,56??? Thanks!!! soooooooooooo much lova ya sexies!

Answer 1

8

Answer 2

8

Answer 3

Let's factor these first. 1) 4x (5x+6) 2) 3x (5x^2-6x-1) 3) -34x (x^2-3) 4) 17x (7x^2 - 12x - 1) Looks like the GCF is just x. However, when I look at everyone else, it seems you want the GCF of the terms in each individual one. If that is the case, then the answers are just 1) 4x 2) 3x 3) 34x (I would pull out a -34x here, to remove the negative from the x^2 term) 4) 17x

Answer 4

8

Answer 5

8

Answer 6

To get the greatest common factors of any numbers, break them down into their primes like this:

16 = 2 X 2 X 2 X 2
24 = 2 X 2 X 2 X 3
56 = 2 X 2 X 2 X 7

Now pick out only the primes that are common to each number. In this case, they are
2 X 2 X 2 = 8

8 is your greatest common factor.

Answer 7

OK
Greatest Common Factor

16
|
2-2-2-2

24
|
2-2-2-3

56
|
2-2-2-7

What's common - Three 2's = 2x2x2 = 8

So GCF is 8

------------------
Now --- FYI ---- To get LCD for the three take
What's left, 2,3,7 = 42
and multiply by what is common = 8
= 336

16 into 336 = 21
24 into 336 = 14
56 into 336 = 6

Hope that helps!

Answer 8

the answer is 2 because 2 is the highest that all of the numbers can be multiplied by.

Answer 9

YOu want the largest number that goes into each. In this case it is 8

16=2x2x2x2
24=2x2x2x3
56=2x2x2x7

each number has 2x2x2

Answer 10

8 is the greatest (largest) number that divides all of them, so it is 8.
