The GCF of 34, 85, and 102 is 17.

The greatest common factor of 85 and 255 is 85.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 34, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 12 and 34 are 1 and 2; the greatest common factor is 2. The common factors of 34 and 40 are 1 and 2; the greatest common factor is 2. The common factors of 34 and 85 are 1 and 17; the greatest common factor is 17. The common factors of 34 and 91 are only 1; the greatest common factor is 1.

The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.
