2838

2838 is a natural number that sits between 2837 and 2839. It is an even, composite integer with prime factorization 2 × 3 × 11 × 43, which makes it square-free. Consequently, it has 16 positive divisors, including 1 and itself: 1, 2, 3, 6, 11, 22, 33, 43, 66, 86, 129, 258, 473, 946, 1419, and 2838.

Its digits sum to 21, so 2838 is divisible by 3 but not by 9. It is divisible by 6 since it is even and a multiple of 3. Because its prime factors are distinct, Euler's totient function yields φ(2838) = 840.

In common numeral systems, 2838 equals 0xB16 in hexadecimal; in binary it is 101100010110; and in octal it is 5426. These representations reflect its factorization properties and help illustrate how a single integer can be expressed across different bases.
