What is 117 in Roman Numerals?

You've likely seen royal titles, such as Henry VIII, and wondered what those symbols represented. Those are Roman numerals. In earlier times, people used fingers, sticks, bones, etc., for counting. As life became more complex, a standardized form like Roman numerals became necessary. The symbols I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are used in this system.

 

In Roman numerals, we use CXVII to represent 117, where C is 100, X is 10, V is 5, and I is 1. Let’s learn more about Roman numerals and how we write them.117 in roman numerals

Basic Rules for 117 in Roman Numerals

There are certain basic rules for writing numbers in Roman numerals. Let's discuss these rules:

 

Rule 1: Addition Method

 

When a smaller number is placed after a larger number, the values are added. For example, CXVII → C + X + V + I + I → 100 + 10 + 5 + 1 + 1 = 117.

 

Rule 2: Repetition Method

 

Roman numerals can be repeated up to three times to form a number. For example, III → 3.

 

Rule 3: Subtraction Method

 

If a smaller numeral precedes a larger one, the smaller number is subtracted from the larger number. For example, IV → V - I → 5 - 1 = 4.

 

Rule 4: Limitation Rule

 

Some symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For instance, we don't write VV for 10; instead, we use X, and for 8, we write VIII, not IIIIIIII.

117 in Roman Numerals by Expansion Method

In the expansion method, a number is broken down based on its place value. Here's how to write 117 in Roman numerals using this method:

 

Step 1: Break the number based on place value: 100 + 10 + 5 + 1 + 1


Step 2: Convert each part into Roman numerals:


- 100 in Roman numerals is C
- 10 in Roman numerals is X
- 5 in Roman numerals is V
- 1 in Roman numerals is I


Step 3: Combine them: C + X + V + I + I = CXVII

117 in Roman Numerals by Grouping Method

When writing a number in Roman numerals, group the numbers:


- 100 + 10 + 5 + 1 + 1
- 100 in Roman numerals is C
- 10 in Roman numerals is X
- 5 in Roman numerals is V
- 1 in Roman numerals is I


So, 117 is written as CXVII.
