Is 860 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 860 is about 29.326.

Thus, the square root of 860 is not an integer, and therefore 860 is not a square number.

What is the square number of 860?

The square of a number (here 860) is the result of the product of this number (860) by itself (i.e., 860 × 860); the square of 860 is sometimes called "raising 860 to the power 2", or "860 squared".

The square of 860 is 739 600 because 860 × 860 = 8602 = 739 600.

As a consequence, 860 is the square root of 739 600.

Number of digits of 860

860 is a number with 3 digits.

What are the multiples of 860?

The multiples of 860 are all integers evenly divisible by 860, that is all numbers such that the remainder of the division by 860 is zero. There are infinitely many multiples of 860. The smallest multiples of 860 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 860). 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 29.326). 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.
