Is 879 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 879 is about 29.648.

Thus, the square root of 879 is not an integer, and therefore 879 is not a square number.

What is the square number of 879?

The square of a number (here 879) is the result of the product of this number (879) by itself (i.e., 879 × 879); the square of 879 is sometimes called "raising 879 to the power 2", or "879 squared".

The square of 879 is 772 641 because 879 × 879 = 8792 = 772 641.

As a consequence, 879 is the square root of 772 641.

Number of digits of 879

879 is a number with 3 digits.

What are the multiples of 879?

The multiples of 879 are all integers evenly divisible by 879, that is all numbers such that the remainder of the division by 879 is zero. There are infinitely many multiples of 879. The smallest multiples of 879 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 879). 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 29.648). 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.
