Find the greatest common factor of each set of numbers 24 40 and 56

To get the greatest common factor of a list of numbers, you can use a neat trick.

First, get the greatest common factor of the first two. Then, the greatest common factor of that and the third, and so on.

In this case, we need to get the greatest common factor of 24 and 40.

I'll use Euclid's algorithm (you can look that up in google, it's just a nice way to find the GCF of two numbers)

24, 40

40, 24

24, 16

16, 8

8, 0

So we get 8. Now we need to get the greatest common factor of 8 and 56:

8, 56

56, 8

8, 0

We get 8 again, and that is the greatest common factor of the three numbers.

Hope this helps :)

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
