736

736 is a natural number that follows 735 and precedes 737. It is even and composite, with a prime factorization of 2^5 × 23. This means its divisors include 1, 2, 4, 8, 16, 32, 23, 46, 92, 184, 368, and 736. The factor 2^5 shows it is divisible by 32 but not by 64.

In numeral systems, 736 has these representations: in binary it is 1011100000; in octal it is 1340; and in hexadecimal it is 0x2E0. In Roman numerals, 736 is written as DCCXXXVI.

From a mathematical viewpoint, 736 is not a prime, nor a triangular or a perfect square. It is a Harshad (or Niven) number in base 10, since the sum of its digits is 7 + 3 + 6 = 16 and 736 is divisible by 16 (736 ÷ 16 = 46). Its prime factorization also implies it cannot be expressed as a sum of two squares, because the prime 23 is congruent to 3 modulo 4 and appears with an odd exponent.

As a number, 736 appears primarily in arithmetic and numeral representations. It serves as an example of a non-prime, composite integer with a simple power–times–prime factorization and multiple standard base representations.
