Respuesta :

the greatest common factor is two 
First, let's look at the Factors of 18 or numbers that can divide into 18 and equal a whole number. These numbers are: 1, 2, 3, 6, 9, and 18

Now for the factors of 22: 1, 2, 11, 22

We can already see a factor that will be the answer. Since the GCF (Greatest Common Factor) of 18 and 22 is 2 and 2 goes into 50, then  your answer will be 2.

Hope this helps!
