## Is 546 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 546 is about 23.367.

Thus, the square root of 546 is not an integer, and therefore 546 is not a square number.

## What is the square number of 546?

The square of a number (here 546) is the result of the product of this number (546) by itself (i.e., 546 × 546); the square of 546 is sometimes called "raising 546 to the power 2", or "546 squared".

The square of 546 is 298 116 because 546 × 546 = 5462 = 298 116.

As a consequence, 546 is the square root of 298 116.

## Number of digits of 546

546 is a number with 3 digits.

## What are the multiples of 546?

The multiples of 546 are all integers evenly divisible by 546, that is all numbers such that the remainder of the division by 546 is zero. There are infinitely many multiples of 546. The smallest multiples of 546 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 546). 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 23.367). 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.
