9407

9407 is a natural number that comes after 9406 and before 9408. In mathematics, it has the prime factorization 23 × 409, making it a semiprime and a square-free composite number. It is odd and not divisible by 2, 3, or 5. The Euler totient function gives φ(9407) = (23 − 1)(409 − 1) = 22 × 408 = 8976. The sum of its digits is 20.

In representations, 9407 in base 16 is 0x24BF, and in binary it is 0010010010111111. These representations reflect its composition from the hexadecimal digits 2, 4, B, and F.

Uses and context-wise, 9407 is commonly cited as an example of a small semiprime in introductory number theory, and it is sometimes employed as a test value in programming exercises. Because it is a relatively small and composite number with exactly two prime factors, it serves as a straightforward case for illustrating factorizations, totients, and related concepts in mathematics education.

As a numeric label, 9407 may be used as a model number, part identifier, or catalog code in various inventories and product lines. Like many four-digit numbers, it can appear in non-mathematical contexts such as dates, identifiers, or organizational numbering schemes, depending on the system in which it is employed.
