## Is 514 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 514 is about 22.672.

Thus, the square root of 514 is not an integer, and therefore 514 is not a square number.

## What is the square number of 514?

The square of a number (here 514) is the result of the product of this number (514) by itself (i.e., 514 × 514); the square of 514 is sometimes called "raising 514 to the power 2", or "514 squared".

The square of 514 is 264 196 because 514 × 514 = 5142 = 264 196.

As a consequence, 514 is the square root of 264 196.

## Number of digits of 514

514 is a number with 3 digits.

## What are the multiples of 514?

The multiples of 514 are all integers evenly divisible by 514, that is all numbers such that the remainder of the division by 514 is zero. There are infinitely many multiples of 514. The smallest multiples of 514 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 514). 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 22.672). 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.
