11 and 22, among others.
The GCF is 11.
GCF(62, 121) = 1. The two numbers are coprime.
11 and 22, among others.
You need at least two numbers to find a GCF. If that's 11 and 9, the GCF is 1.
5 and 11.
The GCF of the given two numbers is 1
11 and 5
The GCF of two prime numbers is 1.
You need at least two numbers to find a GCF. If that's 11 and 23, the GCF is 1.
You need at least two numbers to find a GCF. If that's 11 and 78, the GCF is 858.
This can't be determined. The GCF of 3 and 5 is 1. The GCF of 11 and 33 is 11. There's no rule that covers any and all odd numbers.
The first two are prime so their hcf, and that of all three numbers, is 1.
