Is 846 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 846 is about 29.086.

Thus, the square root of 846 is not an integer, and therefore 846 is not a square number.

What is the square number of 846?

The square of a number (here 846) is the result of the product of this number (846) by itself (i.e., 846 × 846); the square of 846 is sometimes called "raising 846 to the power 2", or "846 squared".

The square of 846 is 715 716 because 846 × 846 = 8462 = 715 716.

As a consequence, 846 is the square root of 715 716.

Number of digits of 846

846 is a number with 3 digits.

What are the multiples of 846?

The multiples of 846 are all integers evenly divisible by 846, that is all numbers such that the remainder of the division by 846 is zero. There are infinitely many multiples of 846. The smallest multiples of 846 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 846). 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 29.086). 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.
