## Is 762 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 762 is about 27.604.

Thus, the square root of 762 is not an integer, and therefore 762 is not a square number.

## What is the square number of 762?

The square of a number (here 762) is the result of the product of this number (762) by itself (i.e., 762 × 762); the square of 762 is sometimes called "raising 762 to the power 2", or "762 squared".

The square of 762 is 580 644 because 762 × 762 = 7622 = 580 644.

As a consequence, 762 is the square root of 580 644.

## Number of digits of 762

762 is a number with 3 digits.

## What are the multiples of 762?

The multiples of 762 are all integers evenly divisible by 762, that is all numbers such that the remainder of the division by 762 is zero. There are infinitely many multiples of 762. The smallest multiples of 762 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 762). 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 27.604). 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.
