## Is 525 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 525 is about 22.913.

Thus, the square root of 525 is not an integer, and therefore 525 is not a square number.

## What is the square number of 525?

The square of a number (here 525) is the result of the product of this number (525) by itself (i.e., 525 × 525); the square of 525 is sometimes called "raising 525 to the power 2", or "525 squared".

The square of 525 is 275 625 because 525 × 525 = 5252 = 275 625.

As a consequence, 525 is the square root of 275 625.

## Number of digits of 525

525 is a number with 3 digits.

## What are the multiples of 525?

The multiples of 525 are all integers evenly divisible by 525, that is all numbers such that the remainder of the division by 525 is zero. There are infinitely many multiples of 525. The smallest multiples of 525 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 525). 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 22.913). 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.
