Is 10889 a prime number? What are the divisors of 10889?

## Is 10889 a prime number?

Yes, 10889 is a prime number.

Indeed, the definition of a prime numbers is to have only two distinct positive divisors, 1 and itself. A number is a divisor of another number when the remainder of Euclid’s division of the second one by the first one is zero. Concerning the number 10889, the only two divisors are 1 and 10889. Therefore 10889 is a prime number.

As a consequence, 10889 is only a multiple of 1 and 10889.

Since 10889 is a prime number, 10889 is also a deficient number, that is to say 10889 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 10889 without 10889 itself (that is 1, by definition!).

## Parity of 10889

10889 is an odd number, because it is not evenly divisible by 2.

## Is 10889 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 10889 is about 104.350.

Thus, the square root of 10889 is not an integer, and therefore 10889 is not a square number.

Anyway, 10889 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 10889?

The square of a number (here 10889) is the result of the product of this number (10889) by itself (i.e., 10889 × 10889); the square of 10889 is sometimes called "raising 10889 to the power 2", or "10889 squared".

The square of 10889 is 118 570 321 because 10889 × 10889 = 108892 = 118 570 321.

As a consequence, 10889 is the square root of 118 570 321.

## Number of digits of 10889
