## Is 795 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 795 is about 28.196.

Thus, the square root of 795 is not an integer, and therefore 795 is not a square number.

## What is the square number of 795?

The square of a number (here 795) is the result of the product of this number (795) by itself (i.e., 795 × 795); the square of 795 is sometimes called "raising 795 to the power 2", or "795 squared".

The square of 795 is 632 025 because 795 × 795 = 7952 = 632 025.

As a consequence, 795 is the square root of 632 025.

## Number of digits of 795

795 is a number with 3 digits.

## What are the multiples of 795?

The multiples of 795 are all integers evenly divisible by 795, that is all numbers such that the remainder of the division by 795 is zero. There are infinitely many multiples of 795. The smallest multiples of 795 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 795). 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 28.196). 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.
