Find the greatest common factor 12v^7y^8 and 18v^2x^6y^3

Question

I need help understanding how to do this 12v^7y^8 and 18v^2x^6y^3 

 

Answer 1

Is this the problem: 12v⁷y⁸ and 18v²x⁶y³?

 

If so, the GCF is 6v²y³

 

The smallest number that divides into 12 and 18 evenly is 6.

To factor variables with exponents, use the variable with the smallest exponent.

Thus, v²and y³.     Both expressions do not contain an "x" term. so you can't factor out an "x."
