397400

397400 is a natural number that sits between 397399 and 397401. It is an even, composite integer with a prime factorization of 2^3 × 5^2 × 1987, where 1987 is itself a prime. This factorization shows that 397400 can be expressed as 200 × 1987, and also as 3974 × 100.

Because of its factorization, 397400 is divisible by 8, 25, and 100, among other divisors. It is also a multiple of 200. The sum of its digits is 3 + 9 + 7 + 4 + 0 + 0 = 23, so the number is not divisible by the digit sum and therefore is not a Harshad number in base 10.

In decimal notation the trailing two zeros reflect its divisibility by 100. The presence of the factor 1987 ties the number to a relatively small prime, while the 2^3 and 5^2 factors highlight its ties to powers of 2 and 5.

Beyond basic arithmetic properties, 397400 can be used as a catalog or identifier in various datasets or systems, but there is no widely recognized mathematical or historical significance unique to this specific value. It serves as a representative example of a composite number with a clear, small prime factor structure.
