Projections of ordinal numbers [closed]

Let $p$ is a product of two non-zero ordinal numbers. Knowing $p$ we can restore each of these two ordinals, right?

How can we denote each of these two ordinals (supposing we know the value of $p$)? I suspect, these may be called "projections", right?

No. $2 \times 3 = 1 \times 6$. –  Zhen Lin Mar 18 '12 at 21:52
No, you can’t always reconstruct $\alpha$ and $\beta$ from $\alpha\cdot\beta$. For example, $n\cdot\omega=\omega$ for every non-zero finite ordinal $n$.
