The GCF of two prime numbers is 1.
Consecutive numbers have a GCF of 1.
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.
No; two numbers can have only 1 GCF.
The GCF of two or more prime numbers is 1 as for example the GCF of 19 and 23 is 1
The GCF of any two consecutive numbers is 1.
The two numbers are coprime so their GCF is 1.
The two numbers are coprime so the gcf is 1.
