Find the greatest common factor!<br> Please help with these 2 questions
Aleksandr-060686 [28]

Hello!

The greatest common factor (GCF) is self explanatory. We find the factors of each number, and find the largest ones that are in common

12: 1,12,2,6,3,4

33:1,33,3,11,

As you can see, the greatest number these two have in common is 3.

Now for the next set.

45: 1,45,3,15,5,9

70:1,70,2,35,5,14,7,10

As you can see, our GCF is 5.

Therefore, our answers are below.

9) 3

10) 5

I hope this helps!

-71.81 \approx 72

-8.02 \approx 9

Her approximation of -8.02 is wrong

Because:

-8.02 \approx 8

<em>Hence (b) is correct</em>
