## Is 616 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 616 is about 24.819.

Thus, the square root of 616 is not an integer, and therefore 616 is not a square number.

## What is the square number of 616?

The square of a number (here 616) is the result of the product of this number (616) by itself (i.e., 616 × 616); the square of 616 is sometimes called "raising 616 to the power 2", or "616 squared".

The square of 616 is 379 456 because 616 × 616 = 6162 = 379 456.

As a consequence, 616 is the square root of 379 456.

## Number of digits of 616

616 is a number with 3 digits.

## What are the multiples of 616?

The multiples of 616 are all integers evenly divisible by 616, that is all numbers such that the remainder of the division by 616 is zero. There are infinitely many multiples of 616. The smallest multiples of 616 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 616). 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 24.819). 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.
