720 is Product of Consecutive Numbers in Two Ways

Theorem

 * $720 = 6 \times 5 \times 4 \times 3 \times 2 = \times 10 \times 9 \times 8$

Proof
Follows from Factorial as Product of Two Factorials:
 * $10! = 6! \times 7!$

and so:
 * $\dfrac {10!} {7!} = 10 \times 9 \times 8 = 6 \times 5 \times 4 \times 3 \times 2 \times 1$

Hence the result.
