437 in Roman Numerals

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 CDXXXVII to represent 437, here CD is 400, XXX is 30, 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 up to three times. XXX → 10 + 10 + 10 = 30

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, CD → D - C → 500 - 100 = 400

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.

Let’s now learn how to write 437 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 437 in Roman numerals using the expansion method. To write 437 in Roman Numerals, follow the steps,

Step 1: The number is broken down based on the place value. Place values are ones, tens, hundreds, etc. For 437, we write it as 400 + 30 + 7

Step 2: Converting the number into Roman Numerals

400 in Roman Numeral — CD

30 in Roman Numeral — XXX

7 in Roman Numeral — VII

Step 3: Combining the Roman Numerals together. Therefore, 437 in Roman Numeral is CD (400) + XXX (30) + VII (7) = CDXXXVII

When writing a large number into Roman Numerals, we group the number. To write 437 in Roman Numerals, we group 437 as 400 + 30 + 7.

400 in Roman Numeral — CD

30 in Roman Numeral — XXX

7 in Roman Numeral — VII

So, 437 is written as CDXXXVII in Roman Numerals.

Roman Numerals follow a certain pattern making it look similar. In this section, we will learn some numbers related to the Roman numeral 437.

• Addition Method: This method is used when a smaller numeral follows a larger numeral, indicating addition. For example, VII = V + I + I = 7

• Subtraction Method: This method is used when a smaller numeral precedes a larger numeral, indicating subtraction. For example, CD = D - C = 400

• Grouping Method: The given numbers are grouped based on their place value and converted into Roman numerals. For example, 437 = 400 + 30 + 7 = CDXXXVII

• Repetition Rule: Certain symbols (I, X, C, M) in the Roman numeric system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times to represent the number 30).

• Limitation Rule: Symbols like V, L, and D cannot be repeated. For example, 10 is written as X, not VV.
