## Is 894 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 894 is about 29.900.

Thus, the square root of 894 is not an integer, and therefore 894 is not a square number.

## What is the square number of 894?

The square of a number (here 894) is the result of the product of this number (894) by itself (i.e., 894 × 894); the square of 894 is sometimes called "raising 894 to the power 2", or "894 squared".

The square of 894 is 799 236 because 894 × 894 = 8942 = 799 236.

As a consequence, 894 is the square root of 799 236.

## Number of digits of 894

894 is a number with 3 digits.

## What are the multiples of 894?

The multiples of 894 are all integers evenly divisible by 894, that is all numbers such that the remainder of the division by 894 is zero. There are infinitely many multiples of 894. The smallest multiples of 894 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 894). 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 29.900). 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.
