## Is 502 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 502 is about 22.405.

Thus, the square root of 502 is not an integer, and therefore 502 is not a square number.

## What is the square number of 502?

The square of a number (here 502) is the result of the product of this number (502) by itself (i.e., 502 × 502); the square of 502 is sometimes called "raising 502 to the power 2", or "502 squared".

The square of 502 is 252 004 because 502 × 502 = 5022 = 252 004.

As a consequence, 502 is the square root of 252 004.

## Number of digits of 502

502 is a number with 3 digits.

## What are the multiples of 502?

The multiples of 502 are all integers evenly divisible by 502, that is all numbers such that the remainder of the division by 502 is zero. There are infinitely many multiples of 502. The smallest multiples of 502 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 502). 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 22.405). 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.
