## Is 304 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 304 is about 17.436.

Thus, the square root of 304 is not an integer, and therefore 304 is not a square number.

## What is the square number of 304?

The square of a number (here 304) is the result of the product of this number (304) by itself (i.e., 304 × 304); the square of 304 is sometimes called "raising 304 to the power 2", or "304 squared".

The square of 304 is 92 416 because 304 × 304 = 3042 = 92 416.

As a consequence, 304 is the square root of 92 416.

## Number of digits of 304

304 is a number with 3 digits.

## What are the multiples of 304?

The multiples of 304 are all integers evenly divisible by 304, that is all numbers such that the remainder of the division by 304 is zero. There are infinitely many multiples of 304. The smallest multiples of 304 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 304). 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 17.436). 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.
