2. Add 3 digits after 325 to form a six-digit number, so that it can be divisible by $3$, $4$, and $5$, and make this value as small as possible. Then this new six-digit number is $\qquad$ _.
【Analysis】First satisfy the divisibility by $4$ and $5$, the unit digit is 0; then to be the smallest, the hundredth digit is 0, and then satisfy the divisibility by 3, the tenth digit is 2. This six-digit number is 325020.
