## Is 876 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 876 is about 29.597.

Thus, the square root of 876 is not an integer, and therefore 876 is not a square number.

## What is the square number of 876?

The square of a number (here 876) is the result of the product of this number (876) by itself (i.e., 876 × 876); the square of 876 is sometimes called "raising 876 to the power 2", or "876 squared".

The square of 876 is 767 376 because 876 × 876 = 8762 = 767 376.

As a consequence, 876 is the square root of 767 376.

## Number of digits of 876

876 is a number with 3 digits.

## What are the multiples of 876?

The multiples of 876 are all integers evenly divisible by 876, that is all numbers such that the remainder of the division by 876 is zero. There are infinitely many multiples of 876. The smallest multiples of 876 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 876). 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 29.597). 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.
