Caroline from Tattingstone and Douglas from Burgoyne Middle School both began by listing the first ten prime numbers:
2,3,5,7,11,13,17,19,23,29.
They then proceeded in the same way:
6469693230/2=3234846615
3234846615/3=1078282205
1078282205/5=215656441
215656441/7=30808063
30808063/11=2800733
2800733/13=215441
215441/17=12673
12673/19=667
667/23=29
29/29=1
And the answer they arrived at was 1!
Clearly worked out - well done.
