Thank you for the opportunity to help you with your question!

Ok, let's notice that 16 and 4 are both multiples of 4. Therefore, the greatest common factor (GCF) would be 4. So if you want to factor the given expression we just need to put the greatest common factor (the 4) at the beginning, then we open parenthesis, we divide each term by the GCF, and we close the parenthesis like this.

16x + 4y = 4(16x/4 + 4y/4) = 4(4x + 1y) = 4(4x + y)

Final answer:

GCF = 4

Factored form:

4(4x + y)

Please let me know if you need any clarification. I'm always happy to answer your questions.
