## Is 829 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 829 is about 28.792.

Thus, the square root of 829 is not an integer, and therefore 829 is not a square number.

Anyway, 829 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 829?

The square of a number (here 829) is the result of the product of this number (829) by itself (i.e., 829 × 829); the square of 829 is sometimes called "raising 829 to the power 2", or "829 squared".

The square of 829 is 687 241 because 829 × 829 = 8292 = 687 241.

As a consequence, 829 is the square root of 687 241.

## Number of digits of 829

829 is a number with 3 digits.

## What are the multiples of 829?

The multiples of 829 are all integers evenly divisible by 829, that is all numbers such that the remainder of the division by 829 is zero. There are infinitely many multiples of 829. The smallest multiples of 829 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 829). 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 28.792). 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.
