A number is given 864
Calculations:
According to the question, we have
The LCM of 864 is,
So, we can write 864 as
864 = 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3
For making cube, make 3 same number pairs
864 = 2 × 2 × 2 × 2 × 3 × 3 × 3 × 2 × 2
Clearly, we can see 2 and 3 make pairs and one pairs of digit 2 has not been fulfilled.
So, We have to multiply 864 by 2, then we get a perfect cube
∴ We have to multiply 864 by 2 to get a perfect cube.
