      The GREATEST common factor is 9     9 x 4 = 36;  9 x 5 = 45.   1 is always the least common factor between/among numbers.

        It seems that 9 is both the greatest common factor AND the greatest common denominator.

        Greatest Common Factor > GCF


        Factors of 36 and 45:


        36: (1, 2, 3, 4, 6, 9, 12, 18, 36)


        45: (1, 3, 5, 9, 15, 45)


        GCF is 9.

              3x3x4 = 36


              3x3x5 = 45


              Therefore, 3 is the greatest common factor
