Is 994 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 994 is about 31.528.

Thus, the square root of 994 is not an integer, and therefore 994 is not a square number.

What is the square number of 994?

The square of a number (here 994) is the result of the product of this number (994) by itself (i.e., 994 × 994); the square of 994 is sometimes called "raising 994 to the power 2", or "994 squared".

The square of 994 is 988 036 because 994 × 994 = 9942 = 988 036.

As a consequence, 994 is the square root of 988 036.

Number of digits of 994

994 is a number with 3 digits.

What are the multiples of 994?

The multiples of 994 are all integers evenly divisible by 994, that is all numbers such that the remainder of the division by 994 is zero. There are infinitely many multiples of 994. The smallest multiples of 994 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 994). 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 31.528). 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.
