## Is 701 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 701 is about 26.476.

Thus, the square root of 701 is not an integer, and therefore 701 is not a square number.

Anyway, 701 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 701?

The square of a number (here 701) is the result of the product of this number (701) by itself (i.e., 701 × 701); the square of 701 is sometimes called "raising 701 to the power 2", or "701 squared".

The square of 701 is 491 401 because 701 × 701 = 7012 = 491 401.

As a consequence, 701 is the square root of 491 401.

## Number of digits of 701

701 is a number with 3 digits.

## What are the multiples of 701?

The multiples of 701 are all integers evenly divisible by 701, that is all numbers such that the remainder of the division by 701 is zero. There are infinitely many multiples of 701. The smallest multiples of 701 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 701). 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 26.476). 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.
