The sum of its decimal digits is 12, so the number is divisible by 3 but not by 9. In Roman numerals it is written MCXXXVII. In binary it equals 10001110001, and in hexadecimal it is 0x471. It lies between 1136 and 1138 in the natural numbers and is the 1,137th positive integer.

1137 may also refer to the year 1137 in the Common Era. This year falls within the High Middle Ages, a period marked by feudal structures, the expansion of towns, and ongoing religious and scholarly activity across different regions. Historical records from around this time describe a variety of political, architectural, and cultural developments, though the year 1137 itself is not singled out by universal consensus as a turning point in broad surveys. Context and significance thus vary by region and source.

In other contexts, 1137 can appear in numerical examples, chronologies, or as a designation in coding or cataloging systems. As a four-digit number and as a specific year, it serves as a reference point in mathematical discussions and historical timelines alike.
