The way I solved it was this:
LCM of 18 , 28 and 35 = 1260
The greatest four digit number possible is 9999
Therefore, 9999/1260 leaves a remainder of 1179.
Subtract 5 from 1179 to yield 1174.
9999 - 1174 = 8825 _________________

Well - you can do it your way. But it took me less than a minute when breaking it down to prime factors. The calculation alone, the way you did it, would've taken me 2 minutes - and that's without reading and trying to figure the darn question out. I'm just lazy and like to do the least amount of calculations when it comes to these problems.
