For your learning there is a better way to find which is a perfect square or not , the way is

now say the number is 1296

jist do as the LCM method like

2 / 1296

2 / 648

2 / 324

2 / 162

9 / 81

9 / 9

1

so the numbers are 2 to the power 4 and 9 to the power 2

now add a root on 2 to the power 4 and 9 to the power 2

so the answer will be 4 multiplied by 9

which is 36

therefore the 36 is the perfect square of 1296.
