## Is 902 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 902 is about 30.033.

Thus, the square root of 902 is not an integer, and therefore 902 is not a square number.

## What is the square number of 902?

The square of a number (here 902) is the result of the product of this number (902) by itself (i.e., 902 × 902); the square of 902 is sometimes called "raising 902 to the power 2", or "902 squared".

The square of 902 is 813 604 because 902 × 902 = 9022 = 813 604.

As a consequence, 902 is the square root of 813 604.

## Number of digits of 902

902 is a number with 3 digits.

## What are the multiples of 902?

The multiples of 902 are all integers evenly divisible by 902, that is all numbers such that the remainder of the division by 902 is zero. There are infinitely many multiples of 902. The smallest multiples of 902 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 902). 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 30.033). 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.
