The numbers three and five have the greatest common factor of one.
Yes, if one of the numbers is a factor of the other.
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.
The GCF of 2 numbers can be 1.
Any consecutive even numbers have a GCF of 2.
14 and 28 are one pair.
The numbers 2 and 30 have a GCF of 2 and an LCM of 30.
The GCF is 2.

2 numbers have a gcf of 3 = 3 & 6, 6 &9,...
The GCF is the smaller number. The GCF of 2 and 4 is 2. The GCF of 3 and 6 is 3. The GCF of 7 and 49 is 7.
The GCF is 2.
the gcf is 2 or 11
