The first step is to find the L.C.M. of the given number
Then last and the final step is to form a pair of numbers and count each pair as one and multiply them.
This will be the final answer.
For Ex
1:)Taking L.C.M. of 121
So we write the factors as . And we get the pair as .
Now we take one factor of the pair , 11
So we get the square root of 121 as 11
