Solution:

Given that,

We have to find the greatest common factor

First find the GCF of numbers 5, 35 and 15

Find the GCF of 5, 35 and 15

The factors of 5 are: 1, 5

The factors of 15 are: 1, 3, 5, 15

The factors of 35 are: 1, 5, 7, 35

Then the greatest common factor is 5

Now find the GCF of variables

Here, the common factor is

Thus, GCF for given expression is:
