## Is 776 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 776 is about 27.857.

Thus, the square root of 776 is not an integer, and therefore 776 is not a square number.

## What is the square number of 776?

The square of a number (here 776) is the result of the product of this number (776) by itself (i.e., 776 × 776); the square of 776 is sometimes called "raising 776 to the power 2", or "776 squared".

The square of 776 is 602 176 because 776 × 776 = 7762 = 602 176.

As a consequence, 776 is the square root of 602 176.

## Number of digits of 776

776 is a number with 3 digits.

## What are the multiples of 776?

The multiples of 776 are all integers evenly divisible by 776, that is all numbers such that the remainder of the division by 776 is zero. There are infinitely many multiples of 776. The smallest multiples of 776 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 776). 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 27.857). 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.
