587 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 587 in Roman Numerals?

The royal titles, such as Henry I, Henry II, and so on, use Roman numerals. Have you noticed these symbols and wondered what they represent? Those are Roman numerals.

 

In ancient times, people counted using fingers, sticks, and bones. As life became more complex, a standard form of counting was needed. Ancient Romans used the Roman numeral system. 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 DLXXXVII to represent 587. D is 500, L is 50, X is 10, and VII is 7. Let’s learn more about Roman numerals and how we write them.

Basic Rules for 587 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. For example, DLXXXVII → D + L + XXX + VII → 500 + 50 + 30 + 7 = 587.

 

Rule 2: Repetition Method

To write larger numbers, 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 in Roman numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9.

 

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, and for 8, we write VIII, not IIIIIIII.

How to Write 587 in Roman Numerals

Let’s now learn how to write 587 in Roman numerals. Follow these methods to write the number in Roman numerals:4

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

587 in Roman Numerals by Expansion Method

In the expansion method, the number is broken down based on place value. In this section, we will learn how to write 587 in Roman numerals using the expansion method. To write 587 in Roman Numerals, follow the steps:

 

Step 1: Break the number based on place value. Place value includes ones, tens, hundreds, etc. For 587, we write it as 500 + 50 + 30 + 7.

 

Step 2: Convert each number into Roman numerals.

  • 500 in Roman Numerals - D

 

  • 50 in Roman Numerals - L

 

  • 30 in Roman Numerals - XXX

 

  • 7 in Roman Numerals - VII

 

Step 3: Combine the Roman numerals together. Therefore, 587 in Roman numerals is D (500) + L (50) + XXX (30) + VII (7) = DLXXXVII.

587 in Roman Numerals by Grouping Method

When writing a large number in Roman numerals, we group the number. To write 587 in Roman numerals, we group 587 as 500 + 50 + 30 + 7.

 

  • 500 in Roman Numerals - D

 

  • 50 in Roman Numerals - L

 

  • 30 in Roman Numerals - XXX

 

  • 7 in Roman Numerals - VII

 

So, 587 is written as DLXXXVII in Roman numerals.

Problem 1

Calculate the sum of DLXXXVII and CXIII.

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

The sum of DLXXXVII and CXIII is DCC.

Explanation

In Roman numerals, DLXXXVII is 587 and CXIII is 113.

The sum of these numbers is 587 + 113 = 700.

700 in Roman numerals can be written as DCC.

Problem 2

A museum has DCCCLXXV artifacts, and it plans to display them in LXXXVII sections. How many artifacts will be in each section?

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

Each section will have X artifacts.

Explanation

To find the number of artifacts in each section, divide the total number of artifacts by the number of sections. DCCCLXXV = 875

LXXXVII = 87

875 / 87 = 10

10 in Roman numerals is X.

Problem 3

Convert the difference between MCM and DLXXXVII into Roman numerals.

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

The difference between MCM and DLXXXVII is MCCCXIII.

Explanation

First, convert the numbers to Arabic numerals:

MCM = 1900

DLXXXVII = 587

The difference is 1900 - 587 = 1313.

1313 in Roman numerals is MCCCXIII.

Problem 4

If you multiply DLXXXVII by II, what is the result in Roman numerals?

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

The result of multiplying DLXXXVII by II is MCLXXIV.

Explanation

First, convert the numbers to Arabic numerals:

DLXXXVII = 587

II = 2

Multiply the numbers: 587 × 2 = 1174

1174 in Roman numerals is MCLXXIV.

Problem 5

Express the result of adding DXLIV and CXLIII using Roman numerals.

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

The result of adding DXLIV and CXLIII is DCLXXXVII.

Explanation

Convert the numbers to Arabic numerals:

DXLIV = 544

CXLIII = 143

Add them together: 544 + 143 = 687

687 in Roman numerals is DCLXXXVII.
