## Is 326 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 326 is about 18.055.

Thus, the square root of 326 is not an integer, and therefore 326 is not a square number.

## What is the square number of 326?

The square of a number (here 326) is the result of the product of this number (326) by itself (i.e., 326 × 326); the square of 326 is sometimes called "raising 326 to the power 2", or "326 squared".

The square of 326 is 106 276 because 326 × 326 = 3262 = 106 276.

As a consequence, 326 is the square root of 106 276.

## Number of digits of 326

326 is a number with 3 digits.

## What are the multiples of 326?

The multiples of 326 are all integers evenly divisible by 326, that is all numbers such that the remainder of the division by 326 is zero. There are infinitely many multiples of 326. The smallest multiples of 326 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 326). 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 18.055). 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.
