Hi Satyaram,
Factorise 840.
840 = 2*2*2*3*5*7
Now from this find the number of ways in which, you can write this as a product of 5 numbers.
You need to do quite a bit of working on this.
Do not forget to include 1s when you are writing it as a product of 5 terms.

From here, you should do the workings.
Hope this helps.

Ashwin (IIT Madras).
