## Is 792 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 792 is about 28.142.

Thus, the square root of 792 is not an integer, and therefore 792 is not a square number.

## What is the square number of 792?

The square of a number (here 792) is the result of the product of this number (792) by itself (i.e., 792 × 792); the square of 792 is sometimes called "raising 792 to the power 2", or "792 squared".

The square of 792 is 627 264 because 792 × 792 = 7922 = 627 264.

As a consequence, 792 is the square root of 627 264.

## Number of digits of 792

792 is a number with 3 digits.

## What are the multiples of 792?

The multiples of 792 are all integers evenly divisible by 792, that is all numbers such that the remainder of the division by 792 is zero. There are infinitely many multiples of 792. The smallest multiples of 792 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 792). 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 28.142). 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.
