(c)cccxlv
In today's representation of Roman numerals: (VI)CCCXLV
The given Roman numerals in today's terms are the equivalent of 345 in Hindu-Arabic numerals.
100345 in Roman numerals is C (100) followed by XXX (30) followed by IV (4) followed by V (5), so it is CXXXIVV.
C represents 100, L is 50, X represents 10, V is 5 and I represents 1. So this would be CXLV.

In today's representation of Roman numerals: (VI)CCCXLV
The given Roman numerals in today's terms are the equivalent of 345 in Hindu-Arabic numerals.
100345 in Roman numerals is C (100) followed by XXX (30) followed by IV (4) followed by V (5), so it is CXXXIVV.
C is 100, X is 10 and V is 5. This would be 345. But that is incorrect. 345 is written as CCCXLV. The X (10) is before the L (50) so it subtracts.
C represents 100, L is 50, X represents 10, V is 5 and I represents 1. So this would be CXLV.
In today's terms 2,345,089,466,345 converted into Roman numerals works out as: (MMCCCXLV)(M)(LXXXIX)M(CDLXVI)CCCXLV Numerals in brackets indicate multiplication by a thousand and superscript numerals indicate multiplication by that particular numeral. Hence: (MMCCCXLV)(M) = 2,345*1,000*1,000,000 = 2,345,000,000,000 (LXXXIX)M = 89*1,000*1,000 = 89,000,000 (CDLXVI) = 466*1,000 = 466,000 CCCXLV = 345 In reality the above number would have probably been rounded off to the nearest billion or trillion.
The Roman numerals for the numbers 1, 2, 3, 4, and 5 are...1 = I2 = II3 = III4 = IV (or IIII)5 = Vand the number 12345 would be represented by the Roman numeral (XII)CCCXLV
Using standard notation, you would need 275 m symbols in succession (m=1,000), followed by cccxlv (345). However, the accepted convention does not permit any symbol to be repeated more than 3 times in succession, including m. This is understandable when you realise a large number such as 1,000,000 would require 1,000 m symbols, which is clearly impractical. However, there is another convention that replaces D (D=500), with its original symbol, |ᴐ, while M is replaced with c|ᴐ. Under this system, large numbers can be notated more easily, by extending the symbol on both sides. Thus cc|ᴐᴐ represents 10,000 while ccc|ᴐᴐᴐ represents 100,000. Moreover, adding an extra ᴐ to the right adds 500, while adding ᴐᴐ would add 5,000, and so on. Thus 275,345 could be represented by the following Roman numeral: ccc|ᴐᴐᴐᴐᴐᴐccc|ᴐᴐᴐᴐᴐcc|ᴐᴐᴐᴐ|ᴐᴐcccxlv To make it clearer, let's separate each symbol. ccc|ᴐᴐᴐᴐᴐᴐ ccc|ᴐᴐᴐᴐᴐ cc|ᴐᴐᴐᴐ |ᴐᴐ ccc xl v ccc|ᴐᴐᴐᴐᴐᴐ = 150,000 ccc|ᴐᴐᴐᴐᴐ = 105,000 cc|ᴐᴐᴐᴐ = 15,000 |ᴐᴐ = 5,000 ccc = 300 xl = 40 v = 5 = 275,345 When using capitals, c|ᴐ is usually replaced with ↀ, which is often credited as the basis for the infinity symbol, ∞.
If you ment one and 400, it's I and CD. If you ment 1,400, it's MCD
