Answer:
C
Step-by-step explanation:
Everything in choice A is divisible by 2
Everything in choice B is divisible by 3
9 and 16 have no common factors, therefore choice C is your answer.
This is about greatest Common factor (G.C.F).
Option C does not have a greatest common factor.
- Greatest common factor between 2 or more numbers is simply the greatest factor that is common to all the numbers.
- Option A; 2 x 2 + 8 x + 4
In this, we can see that 2 is the only common factor between all the numbers.
Thus, the GCF = 2.
So this has a GCF
- Option B: 3x² - 12
Factors of 3 are 1, 3
Factors or 12 are; 1, 2, 3, 4, 6, 12
The highest common factor is 3.
Thus, this has GCF.
- Option C; 9 × 2 - 16
The factors of 9 are; 1, 3, 9
Factors of 2 are; 1, 2
Factors of 16 are; 1, 2, 4, 8, 16
There is no highest common factor here as 1 is not considered to be a highest common factor even though it is a factor.
