The answer is 99856 which is a square of +316 or -316.
Since
99856= \sqrt{2 ^{4} *  79^{2} } =2²*79=316.
And , we see that 99856 is the closest required number to 99999 , which is the largest 5 digit no.
So the required number is 99856
--------------------------------------------------
Note:This can be done in 3 different methods:
1>Prime Factorization
2>Trial and Error
3>Division

TPS: you should first try to find the square root of the "greatest five-digit number" which would be 316 point something. then you should find the square of 316 which will be the answer.
TPS: no one can just guess the number 99856 or 316 naa...you have to find it..
AcharyaVII: Yes it can be done easily in the division method but unfortunately , i can't show it here:(
