## Is 498 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 498 is about 22.316.

Thus, the square root of 498 is not an integer, and therefore 498 is not a square number.

## What is the square number of 498?

The square of a number (here 498) is the result of the product of this number (498) by itself (i.e., 498 × 498); the square of 498 is sometimes called "raising 498 to the power 2", or "498 squared".

The square of 498 is 248 004 because 498 × 498 = 4982 = 248 004.

As a consequence, 498 is the square root of 248 004.

## Number of digits of 498

498 is a number with 3 digits.

## What are the multiples of 498?

The multiples of 498 are all integers evenly divisible by 498, that is all numbers such that the remainder of the division by 498 is zero. There are infinitely many multiples of 498. The smallest multiples of 498 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 498). 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 22.316). 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.
