## Is 582 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 582 is about 24.125.

Thus, the square root of 582 is not an integer, and therefore 582 is not a square number.

## What is the square number of 582?

The square of a number (here 582) is the result of the product of this number (582) by itself (i.e., 582 × 582); the square of 582 is sometimes called "raising 582 to the power 2", or "582 squared".

The square of 582 is 338 724 because 582 × 582 = 5822 = 338 724.

As a consequence, 582 is the square root of 338 724.

## Number of digits of 582

582 is a number with 3 digits.

## What are the multiples of 582?

The multiples of 582 are all integers evenly divisible by 582, that is all numbers such that the remainder of the division by 582 is zero. There are infinitely many multiples of 582. The smallest multiples of 582 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 582). 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 24.125). 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.
