The GCF is 1.
The greatest common factor of 27 and 36 is 9.
The greatest common factor of 14 and 27 is 1.
The greatest common factor of 20 and 27 is 1.To answer this we must begin by factoring both 20 and 27:The factor pairs of 20 are (1,20), (2,10), and (4,5). The prime facrorization is 2*2*5.The factor pairs of 27 are (1,27), (3,9). The prime factorization is 3*3*3.Now we look to see what factors are common, or what factors are in both trees? With these two numbers the only common factor and the greatest common factor are the same - 1.
Since 27 is a factor of 54, and 27 cannot have a larger factor than itself, the greatest common factor of 27 and 54 is 27.

The GCF is 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.
