Is 624 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 624 is about 24.980.

Thus, the square root of 624 is not an integer, and therefore 624 is not a square number.

What is the square number of 624?

The square of a number (here 624) is the result of the product of this number (624) by itself (i.e., 624 × 624); the square of 624 is sometimes called "raising 624 to the power 2", or "624 squared".

The square of 624 is 389 376 because 624 × 624 = 6242 = 389 376.

As a consequence, 624 is the square root of 389 376.

Number of digits of 624

624 is a number with 3 digits.

What are the multiples of 624?

The multiples of 624 are all integers evenly divisible by 624, that is all numbers such that the remainder of the division by 624 is zero. There are infinitely many multiples of 624. The smallest multiples of 624 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 624). 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 24.980). 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.
