The GCF is 1.

12 & 16

If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.

14 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name. All even numbers (except 2) are composite, because they are divisible by 2.

Its factors are: 1 2 4 19 38 and 76 Prime numbers: 2 and 19 Composite numbers: 4 38 and 76 Note: 1 is neither a prime or composite number

The GCF of 2 numbers can be 1.

I take it you are asking for an example, not a definition. Okay. Here are 2: 4 and 9.

The numbers need not have any common factor other than 1. For example, consider 2*5 = 10 and 3*7 = 21. 10 and 21 are both composite but their GCF = 1. They are said to be relatively prime or coprime. No.

The GCF of 2 and 19 is 1. The GCF can't be larger than the smaller of the two numbers. Since 19 is not even, the GCF is 1, and the numbers are coprime.
