# How to find square root using prime factorisation

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
$11\mid\underline{121}$
$11$
So we write the factors as $11*11$. And we get the pair as $\overline{11*11}$.
Now we take one factor of the pair ,$i.e$ 11
So we get the square root of 121 as 11
