    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.

    Not that difficult, is it?

    9

    3x3x4 = 36


    3x3x5 = 45


    Therefore, 3 is the greatest common factor

    3

    The greatest common denominator is 36x45=1620
