Is 548 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 548 is about 23.409.

Thus, the square root of 548 is not an integer, and therefore 548 is not a square number.

What is the square number of 548?

The square of a number (here 548) is the result of the product of this number (548) by itself (i.e., 548 × 548); the square of 548 is sometimes called "raising 548 to the power 2", or "548 squared".

The square of 548 is 300 304 because 548 × 548 = 5482 = 300 304.

As a consequence, 548 is the square root of 300 304.

Number of digits of 548

548 is a number with 3 digits.

What are the multiples of 548?

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 548). 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 23.409). 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.
