## Is 834 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 834 is about 28.879.

Thus, the square root of 834 is not an integer, and therefore 834 is not a square number.

## What is the square number of 834?

The square of a number (here 834) is the result of the product of this number (834) by itself (i.e., 834 × 834); the square of 834 is sometimes called "raising 834 to the power 2", or "834 squared".

The square of 834 is 695 556 because 834 × 834 = 8342 = 695 556.

As a consequence, 834 is the square root of 695 556.

## Number of digits of 834

834 is a number with 3 digits.

## What are the multiples of 834?

The multiples of 834 are all integers evenly divisible by 834, that is all numbers such that the remainder of the division by 834 is zero. There are infinitely many multiples of 834. The smallest multiples of 834 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 834). 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 28.879). 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.
