9. ( 3 x 9 = 27; 16 x 9 = 144. 3 won't go into 16, so can't get a bigger common factor )
The GCF for 20 and 27 is 1.
GCF for 16 & 27 = 1Prime factorization of:16 = 2 * 2 * 2 * 227 = .................3 * 3 * 3=================GCF = 1 (since the twonumbers haveno common factor except 1)
The numbers 16 and 27 don't have any common prime factors. 16 = 2 x 2 x 2 x 2 27 = 3 x 3 x 3 Therefore, the numbers are relatively prime and their greatest common factor is 1. Another way to approach this is to look at the difference between 16 and 27, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. The greatest common factor of two numbers must also be a factor of the difference between the numbers. The difference, 11, is a prime number, so the greatest common factor must be either 11 or 1. Since the numbers are not evenly divisible by 11, so the greatest common factor is 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 highest common factor of 81 and 27 is 27
Yes. The factors of 16 are 1,2,4,8,16 and the factors of 27 are 1,3,9,27 making 1 their only common factor. This makes them relatively prime.
The greatest common factor of 27 and 36 is 9.
