Verified Answer :

The answer is A. x^5

To get the GCF of the two values, it is best to get the invidivual GCFs from the numbers and variables.

19 and 3 do not have a GCF. So, the next GCF to get is between x^7 and x^5. The GCF for both is x^ 5.

Answer:

A. \(x^5\)

Step-by-step explanation:

We are asked to find the greatest common factor of \(19x^7\) and \(3x^5\).

Factors of \(19x^7\): \(19\cdot x^5\times x^2\)

Factors of \(3x^5\): \(3\cdot x^5\)

We can see that both terms share a common factor that is \(x^5\), therefore, the greatest common factor of both terms is \(x^5\).
