Answer:

The least number which must be subtracted from 438867 to make it a perfect square is 623

A number ending in 2, 3, 7 or 8 is never a perfect square.

Hence, we can say 438867 is not a perfect square as it ends with '7'.

Now if we use long division method to find square root of 438867, we get quotient 662 and remainder of 623.

Therefore, 623 is the least number that must be subtracted from 438867 to make it a perfect square. its square root is the quadrant obtained on division.

438867 - 623 = 438244

√(4398244)= 662
