Hello, thanks for responding to my question.
Hello and thanks for responding
\[72 = 2 \times 2 \times 2 \times 3 \times3\]\[78 = 2 \times 3 \times 13\]what factors do 72 and 78 have in common?
Wowwww, so its the numbers 2 and 3, not just one of the numbers?
2 times 3 = 6 = gcf ~ 6 is the gcf
So is 6 the GCF for both numbers
now that was a little confusing!! lol
72 can divide by 1, 2, 3, 4, 6, 8, 12, 18, 24, 36, 72 78 can divide by 1, 2, 3, 6, 13, 26, 39, 78. so 6 is the greatest common factors

I got all your notes.. I have one more of these... GCF of 42 and 48.. I'm going to post this question. Maybe you will be able to come back.
we can do that here if you want ~ ur turn to write down factors of 42 and 48, or all the numbers they can divide
when I add another question , it doesn't save the second question to my file/folder. I need to post the question, Give me a second.
