Question

What is the greatest common factor of 19x^7 and 3x^5? A. x5 B. x7 C. 3x5 D. 3x7

Answer 1

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 2

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 $x^5$.
