The Roman numeral “CDXXXVII” represents the number 437. Here’s the breakdown:

1. CD: This represents 400. In Roman numerals, “C” stands for 100 and “D” for 500. Placing “C” before “D” means 500 minus 100, which is 400.
2. XXX: This stands for 30. In Roman numerals, “X” represents 10, so “XXX” is 10 + 10 + 10.
3. VII: This represents 7. In Roman numerals, “V” stands for 5 and “I” for 1. So, “VII” is 5 + 1 + 1.

Putting them together, CD (400) + XXX (30) + VII (7) equals 437.
