Answer:
D.
Step-by-step explanation:
We are asked to find the GCF of .
Since we know that GCF of two numbers is the greatest number that is a factor of both of them.
First of all we will GCF of 44 and 121.
Factors of 44 are: 1, 2, 4, 11, 22, 44.
Factors of 121 are: 1, 11, 11, 121.
We can see that greatest common factor of 44 and 121 is 11.
Now let us find GCF of .
Factors of are:
Factors of are:
We can see that greatest common factor of is .
Now let us find GCF of .
Factors of are:
Factors of are:
We can see that greatest common factor of is .
Upon combining our all GCFs we will get,
Therefore, GCF of is and option D is the correct choice.
