Step-by-step explanation:

10,15,20. Each using 5 as the GCF

25,30,35. The biggest GCF in 25 is 5, in 30 is 6, in 35 7.

So we can't use 6 or 7 as the GCF,

But, we can use 5 as the GCF.

Same with 40, 45, 50.

The GCF of 40 is 8, for 45 is 9, and for 50 is 10.

But then again, those are not common, so 5 it is again.

And this could keep on going but watch out, it might fail!
