## Is 756 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 756 is about 27.495.

Thus, the square root of 756 is not an integer, and therefore 756 is not a square number.

## What is the square number of 756?

The square of a number (here 756) is the result of the product of this number (756) by itself (i.e., 756 × 756); the square of 756 is sometimes called "raising 756 to the power 2", or "756 squared".

The square of 756 is 571 536 because 756 × 756 = 7562 = 571 536.

As a consequence, 756 is the square root of 571 536.

## Number of digits of 756

756 is a number with 3 digits.

## What are the multiples of 756?

The multiples of 756 are all integers evenly divisible by 756, that is all numbers such that the remainder of the division by 756 is zero. There are infinitely many multiples of 756. The smallest multiples of 756 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 756). 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 27.495). 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.
