### Why do this problem?

This problem offers a lot of practice of division as well as revision of ideas about prime numbers in a situation in which children want to get to the answer - much more fun than a page of calculations but just as much practice. It requires a calculator unless someone really relishes long division!

### Key questions

Have you made a list of the first ten prime numbers?
Remember that $1$ is not a prime number.
Which number are you going to divide by first?
How will you know whether you have divided by that number already?

### Possible extension

Learners who find it easy could be encouraged to invent their own similar problems which will give them practice with multiplication as well as division.
