873 in Roman Numerals

Professor Greenline Explaining Math Concepts

Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman numerals are used in royal titles, book names, sequences, and so on. Here we will be discussing Roman numerals, rules, and examples.

What is 873 in Roman Numerals?

Royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these names and wondered what these symbols (I and II) represented? Those are Roman numerals.

 

In ancient times, people used fingers, sticks, bones, etc., to count. As 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 used in this system.

 

In Roman numerals, we use DCCCLXXIII to represent 873. Here, D is 500, CCC is 300, L is 50, XX is 20, and III is 3. Let’s learn more about Roman numerals and how we write them.873 in roman numerals

Basic Rules for 873 in Roman Numerals

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 the smaller number is placed after the larger number, indicating addition. For example, DCCCLXXIII → D (500) + CCC (300) + L (50) + XX (20) + III (3) = 873.

 

Rule 2: Repetition Method

 

To write certain numbers, some Roman numerals can be repeated up to three times. For example, CCC → C + C + C = 300.

 

Rule 3: Subtraction Method

 

If a small number is placed before a larger number, it indicates subtraction. 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 don't write LL for 100 instead we use C, and 8 is written as VIII, not IIIIIIII.

How to Write 873 in Roman Numerals

Let’s now learn how to write 873 in Roman numerals. Follow these methods to write the number in Roman numerals:

 

  • By Expansion Method
  • By Grouping Method
Professor Greenline from BrightChamps

873 in Roman Numerals by Expansion Method

In the expansion method, based on place value, the number is broken down. In this section, we will learn how to write 873 in Roman numerals using the expansion method. To write 873 in Roman numerals, follow these steps:

 

Step 1: Break the number down based on place value: hundreds, tens, ones, etc. For 873, we write it as 800 + 70 + 3.

 

Step 2: Convert each number into Roman numerals:

 

  • 800 in Roman numerals - DCCC
     
  • 70 in Roman numerals - LXX
     
  • 3 in Roman numerals - III

 

Step 3: Combine the Roman numerals together. Therefore, 873 in Roman numerals is DCCC (800) + LXX (70) + III (3) = DCCCLXXIII.

Professor Greenline from BrightChamps

873 in Roman Numerals by Grouping Method

When writing a large number in Roman numerals, we group the numbers. To write 873 in Roman numerals, we group 873 as 800 + 70 + 3.

 

  • 800 in Roman numerals - DCCC
     
  • 70 in Roman numerals - LXX
     
  • 3 in Roman numerals - III

 

So, 873 is written as DCCCLXXIII in Roman numerals.

Problem 1

Calculate the sum of DCCC and LXXIII.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The sum of DCCC and LXXIII is DCCCLXXIII.

Explanation

To find the sum, we add the values of the Roman numerals.

DCCC = 800

LXXIII = 73

800 + 73 = 873

873 in Roman Numerals is DCCCLXXIII.

Problem 2

A historian finds an ancient scroll that records the year DCCCLXXIII. Determine the year in modern numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The year DCCCLXXIII in modern numerals is 873.

Explanation

In Roman numerals,

D = 500,

CCC = 300,

LXX = 70,

III = 3.

Adding these together gives

500 + 300 + 70 + 3 = 873.

Problem 3

Divide the total of MCMXLVI by DCCCLXXIII.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The quotient of MCMXLVI divided by DCCCLXXIII is I with a remainder of DCCCLXXIII.

Explanation

First, convert the Roman numerals to numbers.

MCMXLVI = 1946

DCCCLXXIII = 873

1946 ÷ 873 = 2 remainder 200

The quotient in Roman numerals is I with a remainder of CC.

Problem 4

A collector has DCCCXLVIII rare coins and wants to have a total of DCCCLXXIII. How many more coins does he need?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The collector needs XXV more coins.

Explanation

To find out how many more coins are needed, subtract the number of coins the collector has from the desired total.

DCCCLXXIII = 873

DCCCXLVIII = 848

873 - 848 = 25

25 in Roman numerals is XXV.

Problem 5

Express the result of adding CDXCIII and CCCLXXX in Roman numerals.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The sum of CDXCIII and CCCLXXX is DCCCLXXIII.

Explanation

Convert each numeral to its numeric value.

CDXCIII = 493

CCCLXXX = 380

493 + 380 = 873

873 in Roman numerals is DCCCLXXIII.
