$\fbox {000}$

The product is divisible by $1000$.So,the last three digits of the product must be $000$.

How can I say that the product is divisible by 1000?

How can I say that the product is divisible by 1000?

The product=$1×2×3×...×1000×...×2018$
So,it must be divided by $1000$.

As example $1×2×3×4×5$ is divided by $1,2,3,4,5$.
