A group of 25 friends were discussing a large positive integer. It can be divided by 1, said the first friend. It can be divided by 2, said the second friend. And by 3, said the third friend. And by 4, added the fourth friend. This continued until everyone had made such a comment. If exactly two friends were incorrect, and those two friends said consecutive numbers, what was the least possible integer they were discussing? i got this problem somewhere. wanted to share it 
Approved Tutor Answer14 Years agoThe two friends incorrect were the ones who said 16 and 17. So the no is
1*23*32*52*7*11*13*19*23 = 787386600
I can understand what ur tellin but why is it 16 and 17???
Approved Tutor Answer14 Years agoDude,
That is the essence of this problem.
You should not be asking for the solutions of such problems. You should rather be solving it on your own no matter how long you take to solve it.
Otherwise your problem solving ability will stay at your current problem solving level.

At Ashwin:
Ok.Ill find the reason behind it on my own... :)
I also think Ashwin sir is right...
First try to solve it yourself , it ll surely increase your ability. There exist a solution fr evry prob somewhere but that doesnt really mean that one shouldnt try to solve it and ask fr the solution .
At Swapnil Saxena: Oh K...And Could u give me ur gmail id??? I can send u a request...
At Ashwin : Onaya Paathi sir intaanda!!!!!!!!! 
I know i am wrong but just trying....... is it 2059318800?
Nope :(
