I am thinking of a 7-digit number between 4000000 and 5000000. <br> The digit in the hundreds place has a value of 800. <br> The digit in the ones place is the sum of the factors of 4. <br> The digit in the hundred thousands place is 1 less than the digit in the millions place. <br> The digit in the ten thousands place is the largest 1-digit even number. <br> The digit in the thousands place stands for 0. <br> The digit in the tens place is the difference between the digit in the hundreds place and the digit in the ones place. <br> What is the number? <br> <input min="0" type="number" id ="imp5pg017q2_1" class="lineinput" placeholder="?" />
