CMXVII
917 in Roman numerals is CMXVII.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which happens in this case.

Step-by-step conversion of 917:

1. CM = 1000 - 100 = 900 → subtraction rule used.

2. X = 10 → represents tens.

3. V = 5 → represents units.

4. II = 1 + 1 = 2 → I repeated 2 times.

So, 900 + 10 + 5 + 2 = 917, or CMXVII in Roman numeral form.
