Answer: The greatest common factor is 2.

Step-by-step explanation: We are given to find the greatest common factor of the following expressions:

[tex]E_1=4k,~~E_2=18k^4,~~E_3=12.[/tex]

Greatest Common Factor: The GCF of two or more numbers (expressions) is the greatest factor that divides all the numbers or expressions.

We have

[tex]E_1=4k=2\times 2\times k,\\\\E_2=18k^4=2\times 3\times 3\times k\times k\times k\times k,\\\\E_3=12=2\times 2\times 3.[/tex]

Therefore, the greatest common factor will be

[tex]G.C.F.=2.[/tex]

Thus, the required greatest common factor is 2.
