## Is 366 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 366 is about 19.131.

Thus, the square root of 366 is not an integer, and therefore 366 is not a square number.

## What is the square number of 366?

The square of a number (here 366) is the result of the product of this number (366) by itself (i.e., 366 × 366); the square of 366 is sometimes called "raising 366 to the power 2", or "366 squared".

The square of 366 is 133 956 because 366 × 366 = 3662 = 133 956.

As a consequence, 366 is the square root of 133 956.

## Number of digits of 366

366 is a number with 3 digits.

## What are the multiples of 366?

The multiples of 366 are all integers evenly divisible by 366, that is all numbers such that the remainder of the division by 366 is zero. There are infinitely many multiples of 366. The smallest multiples of 366 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 366). 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 19.131). 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.
