142800

142800 is a positive integer. It lies between 142,799 and 142,801 and is often encountered in mathematical examples involving factorization and divisibility.

Mathematically, 142800 is even and composite. Its prime factorization is 2^4 × 3 × 5^2 × 7 × 17, showing that it has multiple small prime divisors and a relatively large number of divisors. Consequently, 142800 is divisible by 2, 3, 4, 5, 6, 7, 8, 10, 12, 15, 16 and many other integers derived from those factors. It is also a multiple of 100, since it equals 1428 × 100.

As a base-10 number, its digits sum to 15, which makes 142800 a Harshad (Niven) number in base 10: it is divisible by the sum of its digits (142800 ÷ 15 = 9520). The trailing zeros reflect its factorization as 100 × 1428, and thus it is a common exemplar of numbers with trailing zeros in decimal notation.

Beyond arithmetic properties, 142800 does not correspond to a widely recognized constant, year, location code, or named object in standard references. It is primarily encountered as an item in lists of integers with particular divisibility characteristics.
