Question
What least number must be multiplied to 6912 so that the product becomes a perfect Cube?
Hint:
Hint :- By prime Factorize the given number and find the number to be multiplied
The correct answer is: 3
Explanation :-
6912 = 2 × 3456
= 2 × 2 × 1728
= 2 × 2 × 2 × 864
= 2 × 2 × 2 × 2 × 432
= 2 × 2 × 2 × 2 × 2 × 216
= 2 × 2 × 2 × 2 × 2 × 2 ×108
= 2 × 2 × 2 × 2 × 2 × 2 × 2 × 54
= 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 27
= 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 ×3 × 9
= 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3
= 
we know 
is perfect square and to make 
perfect square multiply it with 3
We need to multiply 6912 with 3 to make
