426 in Roman Numerals

Royal titles such as Henry I, Henry II, etc., often use Roman numerals. Have you noticed these symbols and wondered what they represent? These are Roman numerals.

Initially, people counted using fingers, sticks, bones, etc. As life became more complex, a standardized system was needed. Ancient Romans used Roman numerals: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000).

In Roman numerals, we use CDXXVI to represent 426, where CD is 400, XX is 20, and VI is 6. 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, VI → V + I → 5 + 1 = 6

Rule 2: Repetition Method

Certain Roman numerals can be repeated up to three times. For example, XXX → 30.

Rule 3: Subtraction Method

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

Rule 4: Limitation Rule

Symbols cannot be repeated more than three times, and symbols like V, L, and D cannot be repeated. For example, 10 is not VV; it is X. For 8, we write VIII, not IIIIIIII.

Let’s now learn how to write 426 in Roman numerals. Follow these methods to write the number in Roman numerals.

• By Expansion Method
• By Grouping Method

In the expansion method, a number is broken down based on place value. In this section, we will learn how to write 426 in Roman numerals using the expansion method. To write 426 in Roman numerals, follow these steps:

Step 1: Break the number based on place value: hundreds, tens, and ones. For 426, we write it as 400 + 20 + 6.

Step 2: Convert each number into Roman numerals:

400 in Roman numerals - CD

20 in Roman numerals - XX

6 in Roman numerals - VI

Step 3: Combine the Roman numerals: Therefore, 426 in Roman numerals is CD (400) + XX (20) + VI (6) = CDXXVI.

When writing a large number into Roman numerals, we group the number. To write 426 in Roman numerals, group as 400 + 20 + 6.

• 400 in Roman numerals - CD
   
• 20 in Roman numerals - XX
   
• 6 in Roman numerals - VI

So, 426 is written as CDXXVI 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 426.
 

• Addition rule: When a larger numeral is followed by a smaller numeral, add their values. E.g., VI = V + I = 5 + 1 = 6.

• Grouping method: Group numbers based on place value and convert each group to Roman numerals. E.g., 426 = 400 + 20 + 6 = CDXXVI.

• Repetition rule: Certain symbols (I, X, C, M) can be repeated up to three times. E.g., XXX = 30.

• Subtraction rule: When a smaller numeral precedes a larger numeral, subtract it. E.g., IV = 5 - 1 = 4.

• Limitation rule: Symbols like V, L, and D cannot be repeated. E.g., 10 is not VV but X.
