<PRE><B>Question 752394</B>
First of all
 take the lcm of given number and picked out the pairs of same number like this

12150 =2*(3*3)*(3*3)*3*(5*5)
this is the factor of 12150

the alone number which have no pair are 
(2,3)
so multiply  2 and 3 to the 12150

so it will be equal to 72900 which is the complete square  number

if we take square root of this number this will be equal to 270
