697 in Roman Numerals

Royal titles, such as Henry I, Henry II, and so on, employ Roman Numerals. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc., to count. 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 DCXCVII to represent 697, where D is 500, C is 100, X is 10, V is 5, and II is 2.

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 the smaller number is placed after the larger number, then it is the addition method. For example, DCXCVII → D + C + X + V + I + I → 500 + 100 + 10 + 5 + 1 + 1 = 697

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to 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. It is a subtraction method. For example, IX → X - I → 10 - 1 = 9

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 for 8, we write VIII, not IIIIIIII.

Let’s now learn how to write 697 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 697 in Roman numerals using the expansion method. To write 697 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place value that is ones, tens, hundreds, etc. For 697, we write it as 500 + 100 + 90 + 7.

Step 2: Convert the number into Roman Numerals.

• 500 in Roman Numeral - D
   
• 100 in Roman Numeral - C
   
• 90 in Roman Numeral - XC
   
• 7 in Roman Numeral - VII

Step 3: Combine the Roman Numerals together. Therefore, 697 in Roman Numeral is D (500) + C (100) + XC (90) + VII (7) = DCXCVII

When writing a large number into Roman Numerals, we group the number. To write 697 in Roman Numerals, we group 697 as 500 + 100 + 90 + 7.

• 500 in Roman Numeral - D
   
• 100 in Roman Numeral - C
   
• 90 in Roman Numeral - XC
   
• 7 in Roman Numeral - VII

So, 697 is written as DCXCVII 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 697.

• Addition rule: The addition method is used when a large number is followed by a smaller numeral. Here the values are added. For example, DCXCVII = D + C + XC + VII = 500 + 100 + 90 + 7 = 697.
   
• Expansion method: Here the given number is broken down based on place value, and then each part is converted to its Roman numeral equivalent. For example, 697 = 500 + 100 + 90 + 7 = DCXCVII.
   
• Grouping method: The number is grouped into parts that are converted into Roman numerals. For example, 697 = 500 + 100 + 90 + 7 = DCXCVII.
   
• Subtraction rule: Used when a smaller numeral precedes a larger numeral. For example, XC = C - X = 100 - 10 = 90.
   
• Non-repetition rule: Certain symbols (V, L, D) in the Roman numeric system cannot be repeated. For example, we do not write VV for 10; instead, we use X.
