To factor 3y - 15 by separating the greatest common factor (GCF), you need to identify the largest factor that both terms share. In this case, the GCF of 3y and 15 is 3.
Here's how you can factor 3y - 15 by factoring out the GCF:
1. Take out the GCF, which is 3:
3(y - 5)
So, the factored form of 3y - 15 by separating the GCF is 3(y - 5). This means that you can rewrite 3y - 15 as 3 multiplied by the quantity (y - 5).
