## Is 694 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 694 is about 26.344.

Thus, the square root of 694 is not an integer, and therefore 694 is not a square number.

## What is the square number of 694?

The square of a number (here 694) is the result of the product of this number (694) by itself (i.e., 694 × 694); the square of 694 is sometimes called "raising 694 to the power 2", or "694 squared".

The square of 694 is 481 636 because 694 × 694 = 6942 = 481 636.

As a consequence, 694 is the square root of 481 636.

## Number of digits of 694

694 is a number with 3 digits.

## What are the multiples of 694?

The multiples of 694 are all integers evenly divisible by 694, that is all numbers such that the remainder of the division by 694 is zero. There are infinitely many multiples of 694. The smallest multiples of 694 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 694). 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 26.344). 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.
