236

236 is a natural number that follows 235 and precedes 237. It is an even, composite integer and has several simple mathematical properties that are often noted in number theory and arithmetic.

The prime factorization of 236 is 2^2 × 59. Its positive divisors are 1, 2, 4, 59, 118, and 236. The sum of its proper divisors (excluding 236 itself) is 184, which is less than 236, so 236 is a deficient number. It is not a prime, a square, or a member of common small-number sequences such as the Fibonacci or triangular numbers.

In different numeral systems, 236 can be represented as follows: in binary it is 11101100, in octal it is 354, and in hexadecimal it is EC. In Roman numerals, 236 is CCXXXVI.

In the context of calendars, 236 has a role as a day-of-year marker. In a leap year, the 236th day falls on August 23; in a common year, it falls on August 24.

In science and physics, 236 appears as a mass number for certain isotopes, such as uranium-236 and related reaction products. These isotopes are typically short-lived and arise in nuclear reactions rather than as stable constituents.

Overall, 236 is a small, well-defined integer with straightforward factorization, multiple base representations, and occasional relevance in calendar calculations and nuclear physics.
