Answer 1

SOME ONE HELP ME PLEASE(:

Answer 2

I'll do the first one to get you started


We can factor 54 into 9*6


then we can factor 9 into 3*3
then we can factor 6 into 2*3


So 54 = 9*6 = (3*3)*(2*3) = 2*3*3*3


This means that 54 = 2*3*3*3


Use the same technique to factor 45


45 = 3*3*5



So we have

54 = 2*3*3*3
45 = 3*3*5


Now highlight/circle all the terms that are shared between both numbers. There are two 3's shared


So the GCF of 54 and 45 is 3*3 = 9

Answer 3

What? ^ rahul1995
I'm confused

Answer 4

ok just divide both numbers together till they have common factors.
I divided 40 and 10 both by 2 first, getting 20 and 5, now divide both by 5, get 4 and 1. can't divide the further. So 2*5=10 is our answer. It's called long division method (sorry i put 10 instead of 4 in the drawing xD)

Answer 5

this one is correct one
