Hello Dear!!!
Here's your answer....
171500
Firstly,we have to do prime factorization.
171500 = 2^2 × 5^3 × 7^3
Here,
5 and 7 have power 3.
But they should have power 2.... to become perfect square...
Two numbers should have power two...
2*2 = 4
So.... if you divide the number by 4... then you will get perfect square...
