## Is 260 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 260 is about 16.125.

Thus, the square root of 260 is not an integer, and therefore 260 is not a square number.

## What is the square number of 260?

The square of a number (here 260) is the result of the product of this number (260) by itself (i.e., 260 × 260); the square of 260 is sometimes called "raising 260 to the power 2", or "260 squared".

The square of 260 is 67 600 because 260 × 260 = 2602 = 67 600.

As a consequence, 260 is the square root of 67 600.

## Number of digits of 260

260 is a number with 3 digits.

## What are the multiples of 260?

The multiples of 260 are all integers evenly divisible by 260, that is all numbers such that the remainder of the division by 260 is zero. There are infinitely many multiples of 260. The smallest multiples of 260 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 260). 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 16.125). 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.
