The question says that 392 should be multiplied with the smallest no. to make it a perfect cube. When we prime-factorise 392, we get 2*2*2*7*7. In order to make this number a perfect cube, we need to multiply it with 7 to get a perfect cube of 14. The answer to this question should be 7. However, there is no option which has 7. Also, the solution to this question is completely different from the question. SOF, kindly rectify this error, since the question, options and solutions are different from each other.

The question says 392 which should be multiplied by 7 to get a perfect cube. 7 is not in the option and the solution has a different number and shows that the number is divided by 2 to get a perfect cube. The question, options and solution are all contradictory. Kindly rectify sof.
