## Is 604 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 604 is about 24.576.

Thus, the square root of 604 is not an integer, and therefore 604 is not a square number.

## What is the square number of 604?

The square of a number (here 604) is the result of the product of this number (604) by itself (i.e., 604 × 604); the square of 604 is sometimes called "raising 604 to the power 2", or "604 squared".

The square of 604 is 364 816 because 604 × 604 = 6042 = 364 816.

As a consequence, 604 is the square root of 364 816.

## Number of digits of 604

604 is a number with 3 digits.

## What are the multiples of 604?

The multiples of 604 are all integers evenly divisible by 604, that is all numbers such that the remainder of the division by 604 is zero. There are infinitely many multiples of 604. The smallest multiples of 604 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 604). 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 24.576). 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.
