16153

16153 is a natural number that follows 16152 and precedes 16154. It is an odd composite number. Its prime factorization is 29 × 557, making 16153 a semiprime. Consequently, its positive divisors are 1, 29, 557, and 16153.

In base-10 notation, 16153 consists of the digits 1, 6, 1, 5, and 3; the sum of these digits is 16, yielding a digital root of 7. The number is congruent to 1 modulo 4 and modulo 8, and it is congruent to 7 modulo 9.

As a semiprime, 16153 is not prime and has exactly four divisors. Semiprimes are of interest in elementary number theory and can serve as simple examples in discussions of prime factorization and divisor counts; however, 16153 itself is too small to be used in modern cryptographic applications, which require much larger primes.

Beyond pure mathematics, 16153 may be used as an identifier in various systems, such as catalog numbers, file references, or database keys, where it functions as an arbitrary numeric label rather than carrying intrinsic mathematical meaning.
