221936

221936 is a natural number that follows 221935 and precedes 221937. In mathematics, it is an even composite number with a straightforward prime factorization.

Its prime factorization is 2^4 × 11 × 13 × 97. This implies divisibility by 2, 4, 8, and 16, as well as by 11, 13, and 97, and by their products (for example, 143 = 11 × 13 and 1,067 = 11 × 97). The full factorization shows that 221936 = 16 × 13,871, with 13,871 = 11 × 1,261 and 1,261 = 13 × 97. Hence the number has multiple nontrivial divisors and is not prime.

Representations: In binary it is 110110001011110000 (the trailing four zeros reflect the factor 2^4). In hexadecimal it is 0x362F0, and in octal it is 661360. These representations reflect the same factorization in different bases and illustrate the number’s structure.

As a plain integer, 221936 does not have widely noted cultural or mathematical significance beyond its basic properties and its role as an example of a composite number with a small prime factorization.
