124 in Roman Numerals

In royal titles, such as Henry I, Henry II, and so on, Roman numerals are used to denote order. Earlier people counted using fingers, sticks, bones, etc. As life became more complex, a standardized counting system was required. 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 used in this system.

In Roman numerals, we use CXXIV to represent 124. Here, C is 100, XX is 20, and IV is 4. 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 a larger number. For example, CXXIV → C + XX + IV → 100 + 20 + 4 = 124

Rule 2: Repetition Method

To write a large number, there are certain Roman numerals that can be repeated up to three times. For example, XXX → 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 larger number. For example, IV → V - I → 5 - 1 = 4

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 LL for 100; instead, we use C. For 8, we write VIII, not IIIIIIII.
 

Let’s now learn how to write 124 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 124 in Roman numerals using the expansion method.

To write 124 in Roman numerals, follow these steps:

Step 1: Break the number based on place value into hundreds, tens, and units.

For 124, we write it as 100 + 20 + 4.  

Step 2: Convert the numbers into Roman numerals.

 
  100 in Roman numerals — C  
  20 in Roman numerals — XX  
  4 in Roman numerals — IV  

Step 3: Combine the Roman numerals together.  

Therefore, 124 in Roman numerals is C (100) + XX (20) + IV (4) = CXXIV  
 

When writing a large number in Roman numerals, we group the number. To write 124 in Roman numerals, we group it as 100 + 20 + 4.

100 in Roman numerals — C  
20 in Roman numerals — XX  
4 in Roman numerals — IV  

So, 124 is written as CXXIV 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 124.

• Addition rule: The addition method is used when a large number is followed by a smaller numeral, and the values are added. For example, CXXIV = C + XX + IV = 100 + 20 + 4 = 124.  
   
• Grouping method: The given number is grouped based on its place value and then converted into Roman numerals. For example, 124 = 100 + 20 + 4 = CXXIV.  
   
• Repetition rule: Certain symbols (I, X, C, M) in the Roman numeral system can be repeated only up to three times. For example, XXX = 30 (X is repeated three times).  
   
• Subtraction rule: When a smaller numeral precedes a larger numeral, the smaller numeral is subtracted from the larger one. For example, IV = V - I = 4.  
   
• Place value: Understanding place value is crucial in converting numbers to Roman numerals, as each digit is represented by different symbols based on hundreds, tens, and units.
