32
32 is a even composite number that follows 31 and precedes 33. It is composed of 6 distinct factors: 1, 2, 4, 8, 16, 32. Its prime factorization can be written as 2^5. 32 is classified as a deficient number based on the sum of its proper divisors. In computer science, 32 is represented as 100000 in binary and 20 in hexadecimal. Historically, it is written as XXXII in Roman numerals.

Timeline
Deep dive
How 32 breaks down
32 carries 6 distinct factors and a digit signature of 5 (5 as the digital root). The deficient classification indicates that its proper divisors sum to 31, which stays below the number, offering a quick glimpse into its abundance profile.
Numeral conversions provide additional context: the binary form 100000 supports bitwise reasoning, hexadecimal 20 aligns with computing notation, and the Roman numeral XXXII keeps the encyclopedic tradition alive. These attributes make 32 useful for math olympiad problems, puzzle design, and code challenges alike.
Context
Where 32 shows up
Engineers lean on the divisibility profile when sizing circuits, mod designers use neighboring values (27–37) to tune search ranges, and educators feature 32 in worksheets about factor trees. Its binary footprint of length 6 bits also makes it a solid example for teaching storage limits and overflow.
