458 in Roman Numerals

In royal titles, such as Henry I, Henry II, and so on, Roman numerals are used to denote order. Have you noticed the names and wondered what these symbols (I and II) represented? Those are Roman numerals.

Earlier, people used fingers, sticks, bones, etc., to count. When life became more complex, a standard form was required for counting. Ancient Romans used the Roman numeral system for this purpose. 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 CDL VIII to represent 458. C is 100, D is 500, L is 50, and VIII is 8. Let’s learn more about Roman numerals and how to 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 a larger number. For example, VIII → V + III → 5 + 3 = 8

Rule 2: Repetition Method

To write a larger number, certain Roman numerals can be repeated up to three times. III → 3.

Rule 3: Subtraction Method

If a smaller number precedes a larger number in Roman numerals, we subtract the smaller number from the larger number. For example, XL → L - X → 50 - 10 = 40

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, 20 is written as XX, not VVVV.

Let’s now learn how to write 458 in Roman numerals. Follow these methods to write the number in Roman numerals:

• By Expansion Method 
• By Grouping Method

In the expansion method, the number is broken down based on place value. Here, we will learn how to write 458 in Roman numerals using the expansion method. To write 458 in Roman numerals, follow these steps:

Step 1: Break the number based on place value (ones, tens, hundreds, etc.). For 458, we write it as 400 + 50 + 8.

Step 2: Convert each part into Roman numerals: 400 in Roman numerals — CD 50 in Roman numerals — L 8 in Roman numerals — VIII

Step 3: Combine the Roman numerals together. Therefore, 458 in Roman numerals is CD (400) + L (50) + VIII (8) = CDLVIII

When writing a large number into Roman numerals, we group the number. To write 458 in Roman numerals, we group it as 400 + 50 + 8.

• 400 in Roman numerals - CD
   
• 50 in Roman numerals - L
   
• 8 in Roman numerals - VIII

So, 458 is written as CDLVIII 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 458: 

• Addition Rule: The addition method is used when a larger number is followed by a smaller numeral; the values are added. For example, VIII = V + III = 5 + 3 = 8.
   
• Grouping Method: Here, the given numbers are grouped based on their place value, and then each group is converted into its Roman numerals. For example, 458 = 400 + 50 + 8 = CDLVIII.
   
• 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: The subtraction method is used when a smaller numeral precedes a larger one, and the smaller is subtracted from the larger. For example, XL = L - X = 50 - 10 = 40.
   
• Symbols: The basic symbols in Roman numerals are I, V, X, L, C, D, and M, representing 1, 5, 10, 50, 100, 500, and 1000, respectively.
