Answer 1

324/2=162
162/2=81
81/3=27
27/3=9
9/3=3

324=3×3×3×2×2×3
so 324 requires 2 and 3,3 to make triple pare.
so the least no.=2×3×3=18
we need to multiply 324 by 18 to get a perfect cube.

Answer 2

Step-by-step explanation:

Taking LCM

324=3×3×3×3×2×2

Now,

So, 324 needs 2 and 3,3 to make triple pair for making perfect cube
