## Is 899 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 899 is about 29.983.

Thus, the square root of 899 is not an integer, and therefore 899 is not a square number.

## What is the square number of 899?

The square of a number (here 899) is the result of the product of this number (899) by itself (i.e., 899 × 899); the square of 899 is sometimes called "raising 899 to the power 2", or "899 squared".

The square of 899 is 808 201 because 899 × 899 = 8992 = 808 201.

As a consequence, 899 is the square root of 808 201.

## Number of digits of 899

899 is a number with 3 digits.

## What are the multiples of 899?

The multiples of 899 are all integers evenly divisible by 899, that is all numbers such that the remainder of the division by 899 is zero. There are infinitely many multiples of 899. The smallest multiples of 899 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 899). 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 29.983). 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.
