## Is 339 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 339 is about 18.412.

Thus, the square root of 339 is not an integer, and therefore 339 is not a square number.

## What is the square number of 339?

The square of a number (here 339) is the result of the product of this number (339) by itself (i.e., 339 × 339); the square of 339 is sometimes called "raising 339 to the power 2", or "339 squared".

The square of 339 is 114 921 because 339 × 339 = 3392 = 114 921.

As a consequence, 339 is the square root of 114 921.

## Number of digits of 339

339 is a number with 3 digits.

## What are the multiples of 339?

The multiples of 339 are all integers evenly divisible by 339, that is all numbers such that the remainder of the division by 339 is zero. There are infinitely many multiples of 339. The smallest multiples of 339 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 339). 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 18.412). 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.
