305419896

305,419,896 is the decimal value of the hexadecimal constant 0x12345678. This pattern, 12-34-56-78 in hex, is frequently used in computer science literature as a readable example when teaching base conversions, numeric literals, and binary data representation.

In binary, 0x12345678 corresponds to 0001 0010 0011 0100 0101 0110 0111 1000, a 32-bit value commonly used in demonstrations of endianness and memory layout.

In practical computing, 0x12345678 is used in tutorials to illustrate how the same value is stored differently on little-endian versus big-endian architectures: little-endian stores the bytes as 78 56 34 12, while big-endian stores them as 12 34 56 78.

Numerically, the number is even and divisible by 8 as well as by 9 (the digit sum is 45). Its prime factorization is 2^3 × 3^5 × 157,109.

The value is notable primarily as a convenient mnemonic hex pattern and does not correspond to a widely recognized historical event or constant outside educational and illustrative contexts.
