What’s in the box?

https://nrich.maths.org/5576

 

In the picture below, four whole numbers are being put into the box. Inside the box, a multiplication happens to each number, and then four new numbers are tipped out of the box: 56, 24, 112 and 216.

An open box with four question marks going in, then a closed box, then an open box with the numbers 56, 24, 112 and 216 coming out.

What multiplication might have happened to each number inside the box to get the answers in the picture above?
