MATH HELP: ANYONE OVER age 13?

Question

omg plzplzplzplz im running out of time how do u do this, explain if u can....and theres two you can just answer one....

find each greatest common factor.

6,8,12



use prime factoriztion to find each GCF

3y2(the two is an exponent)(like to the power to)
and 24y3(the three is an exponent too)


PLZPLZPLZ any help is apprecated i HATE going in early to get help i hate my teacher

(using factor trees)

Answer 1

6 2 x 3
8 2 x 2 x 2
12 2 x 2 x 3

GCF is 2.

3y2
24y3

3y2 is the GCF

Answer 2

you mean like this?

i will be using the symbol ^ for "to the power of"
gcf (greatest common factor) of 6,8, and 12 is 2
break them down into prime numbers
6 = 2*3
8 = 2*2*2
12 = 2*2*3
the one they all have in common is 2, so that's the answer
3y^2, 24y^3
break them down into factors/prime numbers again
3y^2 = 3*y*y
24y^3 = 2*2*2*3*y*y*y
the one they both have in common is 3*y*y, so 3y^2 is the answer

Answer 3

6 8 12
3x2 2x4 2x3x2


the greatest common factor is two
it is the biggest number that goes into all the other numbers

Answer 4

3y2 is 3y to 2nd power
24y3 is 24y to 3rd power
y is the only thing they have in common Dr. J has a plain answer.

Answer 5

6 = 2*3
8 = 2*2*2
12 = 2*2*3
they have a same number of 2, so their GCF is 2
3y^2 = 3*y*y
24y^3=2*2*2*3*y*y*y
they have a same 3*y*y so their GCF is 3*y*y or 3y^2, you got it ?

Answer 6

The answer to the first question is 2.

Answer 7

Try downloading Math 911 - you can google search for it.

It has a thirty day free trial period and it is (apparently) very good. Good Luck.
