253355429

253355429 is a nine-digit positive integer. In decimal notation its digits are 2, 5, 3, 3, 5, 5, 4, 2, 9.

It is odd and not divisible by 2 or 5. The sum of its digits is 38, which indicates it is not divisible by 3 or 9. A quick divisibility check shows the number leaves a remainder of 5 when divided by 7 and a remainder of 8 when divided by 11, confirming it is not divisible by these primes. The primality of 253355429 is not established here; determining whether it is prime or composite would require a full factorization using computational methods.

As a nine-digit integer with repeated digits (two 2s, two 3s, two 5s) and a non-repeating pattern, it is representative of arbitrary identifiers used in arithmetic examples. In mathematics, numbers of this size often appear in discussions of primality testing, factorization, and numerical properties, though 253355429 itself does not have a widely cited special significance.

Outside of theoretical contexts, 253355429 commonly appears as a sample value in databases, inventory systems, software tests, or educational materials to illustrate numeric formats, id-like strings, or to demonstrate algorithm behavior with large integers. There is no known historical event, mathematical constant, or notable theorem specifically associated with this exact value.
