Problem:
Suppose we write down the smallest (positive) 
-digit, 
-digit, and 
-digit multiples of 
.
Solution 1
The area of the pan is 
= 
. Since the area of each piece is , there are 
pieces. Thus, the answer is 
.
Solution 2
By dividing each of the dimensions by , we get a 
grid which makes 
pieces. Thus, the answer is .
