Is 996 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 996 is about 31.559.

Thus, the square root of 996 is not an integer, and therefore 996 is not a square number.

What is the square number of 996?

The square of a number (here 996) is the result of the product of this number (996) by itself (i.e., 996 × 996); the square of 996 is sometimes called "raising 996 to the power 2", or "996 squared".

The square of 996 is 992 016 because 996 × 996 = 9962 = 992 016.

As a consequence, 996 is the square root of 992 016.

Number of digits of 996

996 is a number with 3 digits.

What are the multiples of 996?

The multiples of 996 are all integers evenly divisible by 996, that is all numbers such that the remainder of the division by 996 is zero. There are infinitely many multiples of 996. The smallest multiples of 996 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 996). 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 31.559). 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.
