This reminds me of the combinatorial theory, specifically a problem of variation. The question:

The product of three consecutive numbers is 3360. What are the numbers?

We can consider it as the number of variations of m elements taken n to n, is equal to the product of n consecutive and decreasing factors starting from , so that:

.

with the following data n= 3 y Vm,3= 3360. So:

It is clear that the cubic equations have 3 possible solutions, one of them is a real number, which is of our interest, therefore by the method of Cardano we can obtain this number:

with R= 1678, Q=-3/9 and a1=-3 we have:

In order for the variation to be fulfilled we have:

It is resolved. by @juancmz

Late reply thou

The three numbers are 14, 15,16

14 * 15 * 16=3360

14,15,&16

Son tres numeros 14, 15 , 16

Son 14 15 16
