How to Write Roman Numerals 1 to 400?
Roman numerals 1 to 400 can be obtained by using any of the two given below methods:
 Method 1: In this method, we break 323 into the least expandable form, write their respective roman letter and add/subtract them, i.e. 323 = 100 + 100 + 100 + 10 + 10 + 1 + 1 + 1 = C + C + C + X + X + I + I + I = CCCXXIII
 Method 2: In this method, we consider the groups of numbers for addition such as: 323 = 300 + 20 + 3 = CCC + XX + III = CCCXXIII
Any of the above two methods can be used for writing Roman Numerals from 1 to 400.

Certain rules are to be followed while writing roman numbers from 1 to 400. These rules are explained here in detail.

 When a smaller letter precedes a bigger letter, the letters are subtracted. For example: CM, C < M, so CM = M  C = 1000  100 = 900.
 When a letter is repeated multiple times, they get added. For example: XXX = X + X + X = 10 + 10 + 10 = 30
 The same letter cannot be used more than three times in succession. V, L, and D cannot be repeated, they appear only once.
Roman Numerals 1 to 400 Examples

Example 1: Find the Value of CCCLXXXIX + (CLVI  XXV) + CCXXIX.
Solution:
Using Roman numerals 1 to 400 chart: CCCLXXXIX = 300 + 80 + 9 = 389, CLVI = 100 + 50 + 6 = 156, XXV = 20 + 5 = 25, CCXXIX = 200 + 20 + 9 = 229.
Therefore, CCCLXXXIX + (CLVI  XXV) + CCXXIX = 389 + (156  25) + 229 = 749
Now, 749 = 500 + 100 + 100 + (50  10) + (10  1) = D + C + C + (L  X) + (X  I) = DCCXLIX 
Example 2: Using Roman numerals 1 to 400 chart, find the product of CCLXXII and I.
Solution:
CCLXXII = 200 + 70 + 2 = 272 and I = 1
Now, CCLXXII × I = 272 × 1 = 272
Since, 272 = 100 + 100 + 50 + 10 + 10 + 1 + 1 = C + C + L + X + X + I + I = CCLXXII
Therefore, the product of CCLXXII and I is CCLXXII. 
Example 3: Using your knowledge of Roman numerals 1 to 400, Find the value of CCLIV  CCXLIX.
Solution:
CCLIV = 200 + 50 + 4 = 254 and CCXLIX = 200 + 40 + 9 = 249. Therefore, CCLIV  CCXLIX = 254  249 = 5.
Now, V = 5 
Example 4: Find all Perfect Cubes between Roman Numerals from 1 to 400.
Solution:
All perfect cubes from 1 to 400 are 1, 8, 27, 64, 125, 216, 343. Therefore, perfect cubes in roman numerals between roman numerals 1 to 400 are I, VIII, XXVII, LXIV, CXXV, CCXVI, CCCXLIII.
