According to the diagram, the only and therefore the largest common factor of 20 and 27 is 1.
the factors of 9 are 1, 3, and 9 The factors of 27 are 1, 3, 9, and 27. The largest factor they have in common (the largest/greatest common factor) is thus 9
They only have one common factor: 1

To find the greatest common factor of two numbers, you first need to split them into their prime factors. In this case, 20 and 27 can be broken down as follows: 20 = 2x2x5 27 = 3x3x3 The next step would be to identify any common factors. In this case there are none. Thus the greatest common factor of 20 and 27 is 1.
The GCF is 1.

The GCF for 20 and 27 is 1.
The greatest common factor is 3.You can check this by looking at all of the factors of 27 and seeing if 60 is divisible by any of them, and picking the largest one.Factors of 27 : 1 , 3 , 960 is divisible by 1 and 3, and of those two 3 is the larger number.
The GCF is 1.
