The GCF is 1.
Since 23 is a prime number, the greatest common factor of the two numbers is 1.
No. The GCF of any two numbers is also a factor of their difference. The difference between consecutive numbers is 1 so their GCF must also be a factor of 1. The only factor of 1 is 1 - and hence the result.
If the GCF of two numbers p and q is 7, then the GCF of p2 and q2 is 14.
You need at least two numbers to find a GCF.
