Question

Provide 3 examples showing that an even number is not always the GCF (greatest common factor) of two numbers.

Answer 1

3 examples is that you can't multiply 1

Answer 2

The best way to show examples is by simplifying fractions, which is the most common use of the greatest common fact (gcf).

$\frac{10}{25}$  gcf=5

$\frac{6}{9}$  gcf=3

$\frac{13}{26}$  gcf=13
