## Is 928 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 928 is about 30.463.

Thus, the square root of 928 is not an integer, and therefore 928 is not a square number.

## What is the square number of 928?

The square of a number (here 928) is the result of the product of this number (928) by itself (i.e., 928 × 928); the square of 928 is sometimes called "raising 928 to the power 2", or "928 squared".

The square of 928 is 861 184 because 928 × 928 = 9282 = 861 184.

As a consequence, 928 is the square root of 861 184.

## Number of digits of 928

928 is a number with 3 digits.

## What are the multiples of 928?

The multiples of 928 are all integers evenly divisible by 928, that is all numbers such that the remainder of the division by 928 is zero. There are infinitely many multiples of 928. The smallest multiples of 928 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 928). 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 30.463). 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.
