56789

56789 is a five-digit integer in base ten. Its digits 5, 6, 7, 8, and 9 form a consecutive increasing sequence, making the number notable for its simple digit pattern.

In mathematics, 56789 is a composite number. Its prime factorization is 109 × 521, so it is a semiprime (the product of two primes). The digit sum is 35, which means it is not divisible by 3, and the last digit being 9 indicates it is odd and not divisible by 5.

Context and usage: Numbers like 56789 are sometimes used in problem sets and demonstrations to illustrate concepts such as factorization, semiprimes, and digit-pattern problems. It can serve as a convenient test value in programming tasks that require integer arithmetic or validation of arithmetic operations.

Other observations: The number has five distinct digits, all of which are consecutive, increasing from 5 to 9. This makes 56789 a simple example for discussions about digit structure, permutations, and patterns in integers.

In summary, 56789 is a modestly interesting five-digit semiprime with a distinctive consecutive-digit pattern, commonly used as a straightforward example in mathematical and computational contexts.
