    The greatest common factor is 17.

    Step-by-step explanation:

    Both 51 and 85 have only two common factors, 1 and 17. Since, 17 is greater than 1, 17 is the greatest common factor.

    17

    Step-by-step explanation:

    The greatest, and only common factor of 51 and 85 (besides for 1) is 17.

    51 / 17 = 3

    85 / 17 = 5

    So, since 17 can evenly divide both these numbers, it is a common factor.
