# Q: How is 456 written in Roman Numerals?

A: CDLVI

A: CDLVI

Roman Numerals are an ancient way of writing numbers that originated in ancient Rome.

It is still used today, but mainly for date purposes (like with Super Bowl L for Super Bowl 50) or for movie series (Star Wars IV - A New Hope).

Here are the main symbols that are used:

1 | 5 | 10 | 50 | 100 | 500 | 1,000 |

I |
V |
X |
L |
C |
D |
M |

1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |

I |
II |
III |
IV |
V |
VI |
VII |
VIII |
IX |

10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 |

X |
XX |
XXX |
XL |
L |
LX |
LXX |
LXXX |
XC |

100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 |

C |
CC |
CCC |
CD |
D |
DC |
DCC |
DCCC |
CM |

For numbers over 1,000, you put a dash over the top of the Roman Numeral to indicate multiplied by 1,000.

5,000 | 10,000 | 50,000 | 100,000 | 500,000 | 1,000,000 |

V |
X |
L |
C |
D |
M |

To convert 456 to Roman Numerals we need to split it up into place values (ones, tens, hundreds, etc.), like this:

Place Value | Number | Roman Numeral |
---|---|---|

Hundreds | 400 | CD |

Tens | 50 | L |

Ones | 6 | VI |

Please note, we skipped place values that equal 0.

You then combine them all together (starting from the top) to get **CDLVI**.
