Is 942 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 942 is about 30.692.

Thus, the square root of 942 is not an integer, and therefore 942 is not a square number.

What is the square number of 942?

The square of a number (here 942) is the result of the product of this number (942) by itself (i.e., 942 × 942); the square of 942 is sometimes called "raising 942 to the power 2", or "942 squared".

The square of 942 is 887 364 because 942 × 942 = 9422 = 887 364.

As a consequence, 942 is the square root of 887 364.

Number of digits of 942

942 is a number with 3 digits.

What are the multiples of 942?

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 942). 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 30.692). 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.
