2009 as a product of its prime factors is 7*7*41. MMVIIII as a product of its prime factors is VII*VII*XXXXI in Roman numerals. Note that XXXXVIIII (49)*XXXXI (41) = MMVIIII (2009) when multiplied out. And that IL (50-1)*XLI (51-10) = IMMX (2010-1) when multiplied out. But they both have the same numerical values. Conventionally accept wisdom tells us that Roman numerals read from left to right and always start with the highest value numeral. 41 can indeed be written as XLI (40 + 1) or as XXXXI (40 + 1), although the former is shorter and more commonly used. 49 can be written as either XLIX (40 + 9), XLVIII (40 + 5 + 4) or even XXXXVIIII (40 + 5 + 4) as you might expect the first of these three alternatives is the common form, as it is the shortest and simplest to write. The propsed alternative of IL is simply wrong. It begins with I (1) which is patently lower in value than L (50), also according to the website Algebra.com... "I may be placed before V or X but should not be placed in front of any higher value numeral," such as L. Additionally the answer to the problem; 2009 should correctly be written as MMIX (2000 + 9) or even MMVIIII (2000 = 5 + 4) but the proposed alternative of IMMX which incorrectly places an I (1) before M (1000) is patently plain wrong.
The prime factors of 2,009 are 7 and 41. 7 x 41 = 287
2009 = 7 * 7 * 41
XLIV(44 in roman numerals).
L = 50 and I = 1
You may be thinking of the copyright year notation, which is classically shown in Roman Numerals. You can also find these notations classically in books' preface pages, names of Kings, Queens, Popes and on clocks. Sporting events also use Roman Numerals. The answer as to why may be more or less: "we've always done it thata way," or similar.

If you are talking about Roman Numerals then it is MMMDCCXXII.
2x3x5x7 = 210 II*III*V*VII = CCX
The Roman numeral MDCLXVI expressed as a product of its prime factors is: II*VII*VII*XVII = MDCLXVI In other words: 2*7*7*17=1666
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ....... The above numbers are known as prime numbers. What they have in common is that each of them have only two factors, the number itself and one. Numbers can be expressed as the product of their prime factors. For example the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24 but only 2 and 3 are called prime factors because they are in fact prime numbers. So 24 expressed as the product of its prime factors is 2x2x2x3 or 23x3. The prime factors of 2310, which is MMCCCX in Roman numerals, are 2, 3, 5, 7 and 11. Therefore: MMCCCX expressed as the product of its prime factors is II*III*V*VII*XI. Note that number 1 is not considered to be a prime number because it has only one factor.
