what is the greatest common factor of 4k, 18k⁴, and 12? 2 4 2k 4k

Explanation:

Step1: Factor each term

• Factor (4k = 2\times2\times k)
• Factor (18k^{4}=2\times3\times3\times k\times k\times k\times k)
• Factor (12 = 2\times2\times3)

Step2: Find the common factors

The common factor among (4k), (18k^{4}) and (12) is (2) (since (k) is not a factor of (12)).

Answer:

A. (2)
