CCXCVI

CCXCVI is the Roman numeral representation of the integer two hundred ninety‑six (296). The number 296 is a positive even integer that lies between 295 and 297. In the decimal system its digit sum is 2 + 9 + 6 = 17.

The prime factorization of 296 is 2³ × 37. Consequently it has eight positive divisors: 1, 2, 4, 8, 37, 74, 148, and 296. The sum of its proper divisors is 274, which is less than 296; hence the number is a deficient number. It is not a perfect or abundant number.

In base‑2 representation, 296 is expressed as 1 001 0100₂. In base‑12 it is 2 A₁₂, where A denotes eleven. In Roman numerals the standard form is CCXCVI. When written in binary, it contains six ones and five zeros.

As a member of various integer sequences, 296 appears in the sequence of composite numbers (its position is the 60th composite), in the list of even numbers that are not the sum of two squares (together with 298, 300, etc.), and it is a member of the sequence of numbers that can be expressed as the sum of two squares in exactly one way (4² + 14²). The number does not have a special designation in any notable mathematical categorization beyond these properties.

In historical context, the year 296 CE corresponded to the era of the Roman Empire, during which several military campaigns were fought on the Rhine frontier. Additionally, the designation 296 has been used for various transportation routes, highways, and postal codes in different countries, though these uses are largely arbitrary and region‑specific.
