7427

7427 is a natural number that comes after 7426 and before 7428. In mathematics, it is a composite number and specifically a semiprime, being the product of two primes: 7 and 1061. Accordingly, its positive divisors are 1, 7, 1061, and 7427, and it has exactly four divisors. The number is odd and not a multiple of 5 or 3, and its digit sum is 20, giving a digital root of 2. It is congruent to 3 modulo 4, since 7427 mod 4 equals 3.

In various numeral systems, 7427 has representations such as binary 11101000000011 and hexadecimal 0x1D03. These representations reflect its binary and base-16 structure, respectively.

No widely recognized mathematical constants or theorems are specifically tied to the number 7427, but its status as a semiprime makes it a simple example in discussions of prime factorization and divisor count. As with many integers, 7427 is used in examples and exercises across number theory to illustrate basic properties of composite numbers, factorization, and modular arithmetic.
