Since they answered wrong or zzzz . GCF of 9 is 3 . [3x3] .. GCF of 8 is 4 . [4x2,2x4]
9 and 8 has no gcf because 9 and 8 has no common fator
the common factor of 9 & 8 is 1
jyt is wrong gcf of 9 is not 3 and the gcf of 8 is not 4 because gcf means greatest common factor one number do not have a common factor
