## Is 327 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 327 is about 18.083.

Thus, the square root of 327 is not an integer, and therefore 327 is not a square number.

## What is the square number of 327?

The square of a number (here 327) is the result of the product of this number (327) by itself (i.e., 327 × 327); the square of 327 is sometimes called "raising 327 to the power 2", or "327 squared".

The square of 327 is 106 929 because 327 × 327 = 3272 = 106 929.

As a consequence, 327 is the square root of 106 929.

## Number of digits of 327

327 is a number with 3 digits.

## What are the multiples of 327?

The multiples of 327 are all integers evenly divisible by 327, that is all numbers such that the remainder of the division by 327 is zero. There are infinitely many multiples of 327. The smallest multiples of 327 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 327). 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 18.083). 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.
