Is 764 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 764 is about 27.641.

Thus, the square root of 764 is not an integer, and therefore 764 is not a square number.

What is the square number of 764?

The square of a number (here 764) is the result of the product of this number (764) by itself (i.e., 764 × 764); the square of 764 is sometimes called "raising 764 to the power 2", or "764 squared".

The square of 764 is 583 696 because 764 × 764 = 7642 = 583 696.

As a consequence, 764 is the square root of 583 696.

Number of digits of 764

764 is a number with 3 digits.

What are the multiples of 764?

The multiples of 764 are all integers evenly divisible by 764, that is all numbers such that the remainder of the division by 764 is zero. There are infinitely many multiples of 764. The smallest multiples of 764 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 764). 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 27.641). 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.
