<PRE><B>Question 657774</B>
&lt;pre&gt;
The largest digit mentioned is hundred millions (in the first clue),
so it is a 9-digit number.  We will fill in the blanks as we go along.

_ _ _, _ _ _, _ _ _

&lt;/pre&gt;
I have 1s in my millions and ones places.
&lt;pre&gt;
_ _ &lt;u&gt;1&lt;/u&gt;, _ _ _, _ _ &lt;u&gt;1&lt;/u&gt;
&lt;/pre&gt;
I have 3 hundreds.
&lt;pre&gt;
_ _ &lt;u&gt;1&lt;/u&gt;, _ _ _, &lt;u&gt;3&lt;/u&gt; _ &lt;u&gt;1&lt;/u&gt; 
&lt;/pre&gt;
I have 4 ten thousands.
&lt;pre&gt;
_ _ &lt;u&gt;1&lt;/u&gt;, _ &lt;u&gt;4&lt;/u&gt; _, &lt;u&gt;3&lt;/u&gt; _ &lt;u&gt;1&lt;/u&gt;
&lt;/pre&gt;
The numbers in my hundred thousands and ten millions place is half my ten thousands digit. 
&lt;pre&gt;
Since the ten thousands digit is 4, those two digits are 2&#39;s.

_ &lt;u&gt;2&lt;/u&gt; &lt;u&gt;1&lt;/u&gt;, &lt;u&gt;2&lt;/u&gt; &lt;u&gt;4&lt;/u&gt; _, &lt;u&gt;3&lt;/u&gt; _ &lt;u&gt;1&lt;/u&gt;
&lt;/pre&gt;
All my other numbers are double my millions digit.
&lt;pre&gt;
Since the millions digit is 1, all the others are 2&#39;s.

&lt;u&gt;2&lt;/u&gt; &lt;u&gt;2&lt;/u&gt; &lt;u&gt;1&lt;/u&gt;, &lt;u&gt;2&lt;/u&gt; &lt;u&gt;4&lt;/u&gt; &lt;u&gt;2&lt;/u&gt;, &lt;u&gt;3&lt;/u&gt; &lt;u&gt;2&lt;/u&gt; &lt;u&gt;1&lt;/u&gt;
