Guest: what is the gcf of 18 35
I think that you mean greatest common factor gcf
What are the factors of 18, (I'm starting with 18 because it is the smallest one)
1 and 18, 2 and 9, 3 and 6 and thats it
lets put them in order
1,2,3,6,9,18
does 18 go into 35-- no,
does 9 go into 35 --no
and just keep working down the list until you find one where you say YES
that will be the GCF
