Is 383 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 383 is about 19.570.

Thus, the square root of 383 is not an integer, and therefore 383 is not a square number.

Anyway, 383 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 383?

The square of a number (here 383) is the result of the product of this number (383) by itself (i.e., 383 × 383); the square of 383 is sometimes called "raising 383 to the power 2", or "383 squared".

The square of 383 is 146 689 because 383 × 383 = 3832 = 146 689.

As a consequence, 383 is the square root of 146 689.

Number of digits of 383

383 is a number with 3 digits.

What are the multiples of 383?

The multiples of 383 are all integers evenly divisible by 383, that is all numbers such that the remainder of the division by 383 is zero. There are infinitely many multiples of 383. The smallest multiples of 383 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 383). 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 19.570). 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.
