Is 885 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 885 is about 29.749.

Thus, the square root of 885 is not an integer, and therefore 885 is not a square number.

What is the square number of 885?

The square of a number (here 885) is the result of the product of this number (885) by itself (i.e., 885 × 885); the square of 885 is sometimes called "raising 885 to the power 2", or "885 squared".

The square of 885 is 783 225 because 885 × 885 = 8852 = 783 225.

As a consequence, 885 is the square root of 783 225.

Number of digits of 885

885 is a number with 3 digits.

What are the multiples of 885?

The multiples of 885 are all integers evenly divisible by 885, that is all numbers such that the remainder of the division by 885 is zero. There are infinitely many multiples of 885. The smallest multiples of 885 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 885). 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 29.749). 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.
