917 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on. Have you noticed the names and wondered what these symbols (I and II) represented? Those are the Roman Numerals.

Earlier people used to count using fingers, sticks, bones, etc. When life became complex, a standard form was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.

In Roman Numerals, we use CMXVII to represent 917, where CM is 900, X is 10, and VII is 7. Let’s learn more about Roman numerals and how we write them.

There are certain basic rules to write a number in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.

Rule 1: Addition Method

The addition method is used when a smaller number is placed after the larger number. For example, VII → V + I + I → 5 + 1 + 1 = 7.

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated three times. III → 3.

Rule 3: Subtraction Method

If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number. For example, CM → M - C → 1000 - 100 = 900.

Rule 4: Limitation Rule

The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X, and 8 we write as VIII, not IIIIIIII.

Let’s now learn how to write 917 in Roman Numerals. Follow these methods to write the number in Roman Numerals.

• By Expansion Method
• By Grouping Method

In the expansion method, based on the place value, the number is broken down. In this section, we will learn how to write 917 in Roman numerals using the expansion method. To write 917 in Roman Numerals, follow the steps,

Step 1: Break the number based on place value. The place values are ones, tens, hundreds, etc. For 917, we write it as 900 + 10 + 7.

Step 2: Convert the number into Roman Numerals.

• 900 in Roman Numeral - CM
   
• 10 in Roman Numeral - X
   
• 7 in Roman Numeral - VII

Step 3: Combine them into Roman Numerals together. Therefore, 917 in Roman Numeral is CM (900) + X (10) + VII (7) = CMXVII.

When writing a large number into Roman Numerals, we group the number. To write 917 in Roman Numerals, we group 917 as 900 + 10 + 7.

• 900 in Roman Numeral - CM
   
• 10 in Roman Numeral - X
   
• 7 in Roman Numeral - VII

So, 917 is written as CMXVII in Roman Numerals.

Roman Numerals follow a certain pattern making them look similar. In this section, we will learn some numbers related to the Roman numeral 917. 

• Addition rule: The addition method is used when a large number is followed by a smaller numeral; here, the values are added. For example, VII = V + I + I = 5 + 1 + 1 = 7.
   
• Grouping method: Here, the given numbers are grouped based on their place value, and then we convert each group into its Roman numerals. For example, 917 = 900 + 10 + 7 = CMXVII.
   
• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, III = 3 (I is repeated three times to represent the number 3).
   
• Subtraction rule: This method applies when a smaller numeral precedes a larger one, indicating subtraction. For example, CM = M - C = 1000 - 100 = 900.
   
• Place value method: Roman numerals are often broken down by their place values for easier conversion, such as breaking down 917 into 900, 10, and 7.
