## Is 730 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 730 is about 27.019.

Thus, the square root of 730 is not an integer, and therefore 730 is not a square number.

## What is the square number of 730?

The square of a number (here 730) is the result of the product of this number (730) by itself (i.e., 730 × 730); the square of 730 is sometimes called "raising 730 to the power 2", or "730 squared".

The square of 730 is 532 900 because 730 × 730 = 7302 = 532 900.

As a consequence, 730 is the square root of 532 900.

## Number of digits of 730

730 is a number with 3 digits.

## What are the multiples of 730?

The multiples of 730 are all integers evenly divisible by 730, that is all numbers such that the remainder of the division by 730 is zero. There are infinitely many multiples of 730. The smallest multiples of 730 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 730). 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 27.019). 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.
