## Is 992 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 992 is about 31.496.

Thus, the square root of 992 is not an integer, and therefore 992 is not a square number.

## What is the square number of 992?

The square of a number (here 992) is the result of the product of this number (992) by itself (i.e., 992 × 992); the square of 992 is sometimes called "raising 992 to the power 2", or "992 squared".

The square of 992 is 984 064 because 992 × 992 = 9922 = 984 064.

As a consequence, 992 is the square root of 984 064.

## Number of digits of 992

992 is a number with 3 digits.

## What are the multiples of 992?

The multiples of 992 are all integers evenly divisible by 992, that is all numbers such that the remainder of the division by 992 is zero. There are infinitely many multiples of 992. The smallest multiples of 992 are:

## How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 992). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 31.496). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
