## Is 432 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 432 is about 20.785.

Thus, the square root of 432 is not an integer, and therefore 432 is not a square number.

## What is the square number of 432?

The square of a number (here 432) is the result of the product of this number (432) by itself (i.e., 432 × 432); the square of 432 is sometimes called "raising 432 to the power 2", or "432 squared".

The square of 432 is 186 624 because 432 × 432 = 4322 = 186 624.

As a consequence, 432 is the square root of 186 624.

## Number of digits of 432

432 is a number with 3 digits.

## What are the multiples of 432?

The multiples of 432 are all integers evenly divisible by 432, that is all numbers such that the remainder of the division by 432 is zero. There are infinitely many multiples of 432. The smallest multiples of 432 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 432). 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 20.785). 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.
