Which is the biggest number in Roman numerals?

Ancient Romans used Latin Letters (I, V, X, L, C, D, M) as their numerals. The biggest letter in Roman Numerals System is M (1000). And also remember that you can use only three same letters together in a row. So, the numerals for 4 (IIII) and 9 (VIIII) are represented by IV and IX. 

The lowest number you can write in Roman Numerals is number I (1). And the largest numeral is MMMCMXCIX (3999).

On the other hand, using the vinculum which is a mathematical symbol used for grouping, you can multiply the numeral by 1000. For instance, if you want to get 1.000.000, you should draw a line top of the numeral M.

The vinculum was in use in the Middle Ages and this was the way to write numbers higher than 3999 in Roman Numerals System.
