It is 7
If you mean 14 and 28 then it is 14
The GCD is: 34
-14 = -1*1428 = 2*14Thus the GCF is 14. Do not be inclined to believe that the GCF is -14. Although -14 may be a common factor, it is less than 14, hence not the greatest common factor.
1428
The GCF of 42 and 70 is 14.42 = 2 x 3 x 770 = 2 x 5 x 7Common factors 2 and 7 = 14Another method: 70 / 42 = 1 r 2842 / 28 = 1 r 1428 / 14 = 2 r 0So The Greatest Common Factor for 42 and 70 is 14.The GCF is 14.
238 doesn't have any factors in that range. 1190 and 1428 are multiples of 238.

By the way I did all of this with a calculator on my computer so whoever asked this question was acting pretty dumb.
476, 952, 1428 and so on.
28 has three factor pairs which are:28 = 1 x 2828 = 2 x 1428 = 4 x 7
The greatest common factor is the highest number that divides exactly into two or more numbers.14: 1, 2, 7, 1428: 1, 2, 4, 7, 14, 2863: 1, 3, 7, 9, 21, 63The GCF of 14, 28 and 63 is 7.The GCF is 7.
