What is the GCF of 51 68 and 85?
The GCF is 17.
What is the greatest common factor of 51 and 85?
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.
What is the GCF for 34 85 68 and 51?
Factors of 34 are 1 , 2 , 17 , 34.Factors of 85 are 1 , 5 , 17 , 85.Factors of 68 are 1 , 2 , 4 , 17 , 34 , 68.Factors of 51 are 1 , 3 , 17 , 51.The Greatest Common Factor is 17
What is the GCF of 85 and 51?
To find the greatest common factor between two numbers, we do the following multiple times:(1) Take the remainder of the larger divided by the smaller(2) If there is no remaineder, the smaller is the GCF.(3) Repeat the process with the smaller number and the remainder.Example: GCF of 18 and 10.18/10=1 R 8. So, we take the GCF of 8 and 10.10/8=1 R 2. We take the GCF of 2 and 8.8/2=4 R 0. By rule #2, 2 is our GCF.Lets use 85 and 51.85/51=1 R 3451/34=1 R 1734/17=2 R 0.Our answer is 17.------------------------------------------------------------------------------------------------Or an easier way to do it is factor trees. 51 85^ ^5 17 3 17The numbers cannot be simplified any more, so there fore the GCF is 17.Factors of 85:1,5,17,51Factors of 51:1,3,17,51Therefore, the greatest common factor is 17.It is: 17
What is the GCF of 75 85 and 95?
