## Is 836 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 836 is about 28.914.

Thus, the square root of 836 is not an integer, and therefore 836 is not a square number.

## What is the square number of 836?

The square of a number (here 836) is the result of the product of this number (836) by itself (i.e., 836 × 836); the square of 836 is sometimes called "raising 836 to the power 2", or "836 squared".

The square of 836 is 698 896 because 836 × 836 = 8362 = 698 896.

As a consequence, 836 is the square root of 698 896.

## Number of digits of 836

836 is a number with 3 digits.

## What are the multiples of 836?

The multiples of 836 are all integers evenly divisible by 836, that is all numbers such that the remainder of the division by 836 is zero. There are infinitely many multiples of 836. The smallest multiples of 836 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 836). 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 28.914). 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.
