please make it brainlist

hope its help u..

first we have to take the l. c. m of 18 to know the least no..

the l. c. m of 18 is 2×3×3

in the factors of 18 two didn't make any pair..

so 2 is the least no. which would be subtracted from 18 to get the perfect square.. 2 answer.. ( 18-2 =16 is the perfect square).

verification :-

18-2=16 lets take the l. c. m of 16.

l. c. m of 16 = 2×2×2×2

here all the factors of 16 make pair..

so it is a perfect square..

hence verified..
