# Can you solve it?

Algebra Level 4

$\large \left \lfloor \dfrac x{1!} \right \rfloor + \left \lfloor \dfrac x{2!} \right \rfloor + \left \lfloor \dfrac x{3!} \right \rfloor +\cdots + \left \lfloor \dfrac x{10!} \right \rfloor =1001$

Find the integer value of $$x$$ satisfying the equation above.

Notations:

• $$\lfloor \cdot \rfloor$$ denotes the floor function.

• $$!$$ denotes the factorial notation. For example, $$8! = 1\times2\times3\times\cdots\times8$$.
