## Is 452 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 452 is about 21.260.

Thus, the square root of 452 is not an integer, and therefore 452 is not a square number.

## What is the square number of 452?

The square of a number (here 452) is the result of the product of this number (452) by itself (i.e., 452 × 452); the square of 452 is sometimes called "raising 452 to the power 2", or "452 squared".

The square of 452 is 204 304 because 452 × 452 = 4522 = 204 304.

As a consequence, 452 is the square root of 204 304.

## Number of digits of 452

452 is a number with 3 digits.

## What are the multiples of 452?

The multiples of 452 are all integers evenly divisible by 452, that is all numbers such that the remainder of the division by 452 is zero. There are infinitely many multiples of 452. The smallest multiples of 452 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 452). 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 21.260). 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.
