## Is 365 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 365 is about 19.105.

Thus, the square root of 365 is not an integer, and therefore 365 is not a square number.

## What is the square number of 365?

The square of a number (here 365) is the result of the product of this number (365) by itself (i.e., 365 × 365); the square of 365 is sometimes called "raising 365 to the power 2", or "365 squared".

The square of 365 is 133 225 because 365 × 365 = 3652 = 133 225.

As a consequence, 365 is the square root of 133 225.

## Number of digits of 365

365 is a number with 3 digits.

## What are the multiples of 365?

The multiples of 365 are all integers evenly divisible by 365, that is all numbers such that the remainder of the division by 365 is zero. There are infinitely many multiples of 365. The smallest multiples of 365 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 365). 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 19.105). 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.
