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.
To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
Two numbers have a GCF. Two sets of two numbers may have the same GCF.
You need at least two numbers to find a GCF.

== == The gcf of two successive natural numbers is always 1. Hence the gcf of 27 & 26 is 1.
You need at least two numbers to find a GCF. If that's 9 and 26, the GCF is 1.
You need at least two numbers to find a GCF.
You need at least two numbers to find a GCF.
The GCF of two prime numbers is 1.
Any two prime numbers, eg 3 and 17 also any two co-prime numbers eg 26 and 33
The GCF of the two numbers is 1. So, 9/26 is the simplest form.
