#### Work Step by Step

Given the numbers $4, 3, 9$ we will use each digit at least two times to write the largest seven-digit number possible. The largest digit is $9$. We will place the largest digit ($9$) in the three largest valued columns (one-million, 100-thousands, and ten-thousands). Next, we will place the second largest digit ($4$) in the next two largest valued columns (thousands and hundreds). Next, we will place the third largest digit ($3$) in the next two largest valued columns (tens and ones). $9994433$ Separate each group of three digits with a comma. $9,994,433$
