13571420

13571420 is a positive integer that appears in decimal notation as an eight-digit number. It is even and ends in a zero, so it is divisible by 2 and by 5 as well as by 10.

Its prime factorization begins with 2^2 × 5 × 678,571, where 678,571 is the remaining cofactor. The cofactor is odd, and its primality is not established here; determining the full factorization would require further testing. In decimal arithmetic, this confirms that 13,571,420 is not a prime number.

In terms of size, 13,571,420 is less than 2^24 (16,777,216), placing it within the range commonly used for 24-bit integers in some computer systems. The sum of its digits is 1+3+5+7+1+4+2+0 = 23, giving a digital root of 5. The square root is approximately 3,684.6, so the number is not a perfect square.

Beyond mathematics, 13571420 may occur as an identifier in databases, catalogs, or records. Without additional context, it has no inherent meaning beyond being an eight-digit numeral. In general usage, such numbers are treated as arbitrary identifiers or data keys rather than mathematical objects with special properties.
