What is the greatest common factor of 4k, 18k^4, and 12?

a) 2

b) 4

c) 2k

d) 4k

greatest common factor is 2

Step-by-step explanation:

the greatest common factor of 4k, 18k^4, and 12

To find GCf we break the factors of each term and check which factor is common for all the three terms

4k : 2*2*k

18k^4 : 3*3*2*k*k * k*k

12 : 3*2*2

Common factor is : 2

we have only 2 in common for all the three terms

So greatest common factor is 2
