Answer 1

Answer:

No it isn't. It should be multiplied by 1.001

Step-by-step explanation:

Largest 3 digit no. = 999

Largest 3 digit no. is not a cube.

9^3 = 729

10^3 = 1000

Closest cube = 1000

The no. by which it should be multiplied =

1000 ÷ 999 = 1.001

Answer 2

The largest 3 digit number is 999

Resolving 999 as a product of prime

999=3×3×3×37

In order to make 999 as a perfect cube it must be divided by 37.

So the least number is 37.
