## Is 703 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 703 is about 26.514.

Thus, the square root of 703 is not an integer, and therefore 703 is not a square number.

## What is the square number of 703?

The square of a number (here 703) is the result of the product of this number (703) by itself (i.e., 703 × 703); the square of 703 is sometimes called "raising 703 to the power 2", or "703 squared".

The square of 703 is 494 209 because 703 × 703 = 7032 = 494 209.

As a consequence, 703 is the square root of 494 209.

## Number of digits of 703

703 is a number with 3 digits.

## What are the multiples of 703?

The multiples of 703 are all integers evenly divisible by 703, that is all numbers such that the remainder of the division by 703 is zero. There are infinitely many multiples of 703. The smallest multiples of 703 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 703). 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 26.514). 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.
