- #1

- 1,631

- 4

then let 1*2*3*4*..............*2004*2005*2006

The question is this, what would be the smallest natural number that you would get, after you do the neccessary calculations?

i got the answer 1.

here is what i did:

(2006-2005)-(2004-2003)-...........-(4-3)+(2-1)=1

so can anyone please comment on my approach?

thnx
