To find : What is the greatest number of platters he can prepare?
Solution :
The greatest number of platters he can prepare is given by finding the GCF of 15 and 6.
Factoring the numbers,
![6=2\times 3](https://tex.z-dn.net/?f=6%3D2%5Ctimes%203)
![15=3\times 5](https://tex.z-dn.net/?f=15%3D3%5Ctimes%205)
The GCF is the greatest common factor.
![GCF(6,15)=3](https://tex.z-dn.net/?f=GCF%286%2C15%29%3D3)
Therefore, the greatest number of platters he can prepare is 3.
