674 in Roman Numerals

The royal titles, such as Henry I, Henry II, and so on, use Roman Numerals. 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 DCLXXIV to represent 674. Here, D is 500, C is 100, L is 50, X is 10, 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, DCLXXIV → D + C + L + X + X + IV → 500 + 100 + 50 + 10 + 10 + 4 = 674

Rule 2: Repetition Method

To write a large number, there are certain Roman Numerals that can be repeated up to three times. For example, XX → 20 (X is repeated twice).

Rule 3: Subtraction Method

If a smaller number is placed before a larger number in Roman Numerals, we subtract the smaller number from the larger one. 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 VV for 10; instead, we use X. For 8, we write VIII, not IIIIIIII.

Let’s now learn how to write 674 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 674 in Roman numerals using the expansion method. To write 674 in Roman Numerals, follow the steps:

Step 1: Break the number based on the place value. Place values are ones, tens, hundreds, etc. For 674, we write it as 600 + 70 + 4

Step 2: Converting the number into Roman Numerals
 

• 600 in Roman Numeral - DC
   
• 70 in Roman Numeral - LXX
   
• 4 in Roman Numeral - IV

Step 3: Combine the Roman Numerals together. Therefore, 674 in Roman Numerals is DC (600) + LXX (70) + IV (4) = DCLXXIV

When writing a large number into Roman Numerals, we group the number. To write 674 in Roman Numerals, we group 674 as 600 + 70 + 4

• 600 in Roman Numeral - DC
   
• 70 in Roman Numeral - LXX
   
• 4 in Roman Numeral - IV

So, 674 is written as DCLXXIV 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 674. 

• Addition rule: This method is used when a large number is followed by a smaller numeral, here the values are added. For example, DCLXXIV = D + C + L + X + X + IV = 674.
   
• Grouping method: Here, the given numbers are grouped based on their place value and then converted into Roman numerals. For example, 674 = 600 + 70 + 4 = DCLXXIV.
   
• 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).
   
• Subtraction rule: This method is used when a smaller number precedes a larger numeral, indicating subtraction. For example, IV = 5 - 1 = 4.
   
• Place value: The value of a digit based on its position within a number. For example, in 674, the digit 6 is in the hundreds place.
