Is 444 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 444 is about 21.071.

Thus, the square root of 444 is not an integer, and therefore 444 is not a square number.

What is the square number of 444?

The square of a number (here 444) is the result of the product of this number (444) by itself (i.e., 444 × 444); the square of 444 is sometimes called "raising 444 to the power 2", or "444 squared".

The square of 444 is 197 136 because 444 × 444 = 4442 = 197 136.

As a consequence, 444 is the square root of 197 136.

Number of digits of 444

444 is a number with 3 digits.

What are the multiples of 444?

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 444). 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 21.071). 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.
