## Is 302 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 302 is about 17.378.

Thus, the square root of 302 is not an integer, and therefore 302 is not a square number.

## What is the square number of 302?

The square of a number (here 302) is the result of the product of this number (302) by itself (i.e., 302 × 302); the square of 302 is sometimes called "raising 302 to the power 2", or "302 squared".

The square of 302 is 91 204 because 302 × 302 = 3022 = 91 204.

As a consequence, 302 is the square root of 91 204.

## Number of digits of 302

302 is a number with 3 digits.

## What are the multiples of 302?

The multiples of 302 are all integers evenly divisible by 302, that is all numbers such that the remainder of the division by 302 is zero. There are infinitely many multiples of 302. The smallest multiples of 302 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 302). 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 17.378). 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.
