## Is 348 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 348 is about 18.655.

Thus, the square root of 348 is not an integer, and therefore 348 is not a square number.

## What is the square number of 348?

The square of a number (here 348) is the result of the product of this number (348) by itself (i.e., 348 × 348); the square of 348 is sometimes called "raising 348 to the power 2", or "348 squared".

The square of 348 is 121 104 because 348 × 348 = 3482 = 121 104.

As a consequence, 348 is the square root of 121 104.

## Number of digits of 348

348 is a number with 3 digits.

## What are the multiples of 348?

The multiples of 348 are all integers evenly divisible by 348, that is all numbers such that the remainder of the division by 348 is zero. There are infinitely many multiples of 348. The smallest multiples of 348 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 348). 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 18.655). 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.
