Assuming you mean 5t^3u^ 3and 18t^8u^5y^6, you are not correct.

The factors of 5t^3u^3 are:  5 x t^3 x u^3
The factors of 18t^8u^5y^6 are 18 x t^8 x u^5 x y^6

GCF = 5 x 18 x t^8 x u^5 x y^6 which is 90 t^8u^5y^6.

The greatest common factor of two (or more) integers is the largest integer that is a factor of both (or all) numbers.

Understand?  Based on this definition, there is nothing that can done with your question.  Please, type the question correctly and get back to us here.

Your answer cannot be right according to the definition of the GCF given above.

GCF stands for Greatest Common Factor
your numbers are 5t^3u^3,18t^8,u^5y^6
So, the GCF is 90t^8u^5y^6

5t^3u^3     18t^8 u^5y^6
greatest common factor is t^3u^3
t^3u^2(5)      t^3u^2(18t^5u^2y^6)
