## Is 837 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 837 is about 28.931.

Thus, the square root of 837 is not an integer, and therefore 837 is not a square number.

## What is the square number of 837?

The square of a number (here 837) is the result of the product of this number (837) by itself (i.e., 837 × 837); the square of 837 is sometimes called "raising 837 to the power 2", or "837 squared".

The square of 837 is 700 569 because 837 × 837 = 8372 = 700 569.

As a consequence, 837 is the square root of 700 569.

## Number of digits of 837

837 is a number with 3 digits.

## What are the multiples of 837?

The multiples of 837 are all integers evenly divisible by 837, that is all numbers such that the remainder of the division by 837 is zero. There are infinitely many multiples of 837. The smallest multiples of 837 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 837). 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 28.931). 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.
