DCCXXXIX

DCCXXXIX is the Roman numeral representation of the number 739. This numeral is constructed using standard Roman numeral symbols. The symbol D represents 500, C represents 100, X represents 10, and IX represents 9. Therefore, DCCXXXIX is formed by adding these values together: 500 + 100 + 100 + 10 + 10 + 10 + 9, which equals 739.

In Roman numeral notation, larger values are generally placed before smaller values. When a smaller numeral is placed before a larger numeral, it indicates subtraction. In the case of DCCXXXIX, the D is followed by two Cs, meaning 500 + 100 + 100. The three Xs signify 10 + 10 + 10. Finally, the IX represents 9, as the I (1) is placed before the X (10), indicating 10 - 1. This additive and subtractive principle is fundamental to interpreting Roman numerals.

The number 739 itself is an integer. It is an odd number and a composite number, as it can be divided evenly by 1, 7, 105.5, and 739. It is also a prime number multiplied by another number. In historical contexts, Roman numerals like DCCXXXIX would have been used for recording dates, quantities, and in various forms of inscription and documentation within the Roman Empire and subsequently in medieval Europe.
