Question

what is the least number by which 3087 must be multiplied to make it a perfect cube​

Answer 1

Answer:

The least number by which 3087 must be multiplied to make a perfect cube is 3

Step-by-step explanation:

Through prime factorisation method

3087÷3=1029

1029÷3=343

343÷7(as 7 is the lowest factor of 7 other than 1)=49

49÷7=7

7÷7=1

Here 7×3 is not possible as digit 3 is repeated only two times

So 3087 should be multiplied with 3 to make it a perfect cube
