92 is a natural number that falls between 91 and 93. It is a composite number, meaning it has divisors other than 1 and itself.
In the decimal number system, 92 consists of two digits: 9 in the tens place and 2 in the ones place. It is an even number, since it is evenly divisible by 2.
Mathematical properties
The divisors of 92 are 1, 2, 4, 23, 46, and 92. The prime factorization is 2 × 2 × 23, which can be written as 2² × 23. The sum of its proper divisors (1 + 2 + 4 + 23 + 46) is 76, which is less than 92; therefore 92 is a deficient number.
92 is an even number that is not a perfect square: the square root of 92 lies between 9 and 10. It also leaves a remainder of 4 when divided by 8 (92 = 8 × 11 + 4).
