874

874 is a natural number that follows 873 and precedes 875. In mathematics it is an even, composite integer.

Its prime factorization is 874 = 2 × 19 × 23. The positive divisors are 1, 2, 19, 23, 38, 46, 437, and 874, for a total of eight divisors. The sum of its proper divisors is 566, which is less than 874, so 874 is a deficient number. It is also a Harshad (Niven) number in base 10 because it is divisible by the sum of its digits: 8 + 7 + 4 = 19, and 874 ÷ 19 = 46.

In various numeral systems, 874 is represented as follows: decimal 874; binary 1101101010; octal 1552; hexadecimal 0x36A; and Roman numerals DCCCLXXIV.
