The factors of 51 are:1, 3, 17, 51The factors of 85 are:1, 5, 17, 85The common factors are:1, 17The Greatest Common Factor:GCF = 17
It is: 5
It is: 5
The GCF is 17.
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.
Factor them. 3 x 17 = 51 5 x 17 = 85 Select the common factor. The GCF is 17.
No, it is 17.
The GCF is 17.
