131072

131072 is an integer equal to 2^17. It is a power of two, which makes it common in computing contexts involving binary addressing and memory sizing.

In base representations, it is written as decimal 131072, binary 100000000000000000, hexadecimal 0x20000, and octal 0o400000. As a data quantity, 131072 bytes equals 128 KiB (kibibytes), since 1 KiB equals 1024 bytes. Thus 131072 bytes is a typical block or buffer size in memory systems.

Mathematically, being 2^17, its divisors are precisely 2^k for k from 0 to 17, giving 18 divisors. It is even and not prime, and its prime factorization contains only the single prime 2 with exponent 17.

Contexts and usage: Because powers of two align with binary addressing, 131072 is a natural size for memory pages, cache lines, or buffers in some systems. In programming and algorithms, lengths that are powers of two simplify bitwise operations and can optimize certain transforms and routines when the required length is 2^n. The number also serves as a convenient reference point in discussions of memory measurement, alignment, and chunk sizing in various computing environments.
