Because ten does not divide into 35 evenly.
The GCF is 1.
The GCF is 7.
The GCF of 35 and 40 is 5. The prime factorization of 35 is 5*7. The prime factorization of 40 is 2*2*2*5 The GCF is 5, which is the only common factor.
All I did was make a factor tree. The GCF (Greatest Common Factor) is 5. :)
