## Is 912 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 912 is about 30.199.

Thus, the square root of 912 is not an integer, and therefore 912 is not a square number.

## What is the square number of 912?

The square of a number (here 912) is the result of the product of this number (912) by itself (i.e., 912 × 912); the square of 912 is sometimes called "raising 912 to the power 2", or "912 squared".

The square of 912 is 831 744 because 912 × 912 = 9122 = 831 744.

As a consequence, 912 is the square root of 831 744.

## Number of digits of 912

912 is a number with 3 digits.

## What are the multiples of 912?

The multiples of 912 are all integers evenly divisible by 912, that is all numbers such that the remainder of the division by 912 is zero. There are infinitely many multiples of 912. The smallest multiples of 912 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 912). 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 30.199). 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.
