Is 10909 a prime number? What are the divisors of 10909?

## Is 10909 a prime number?

Yes, 10909 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 10909, the only two divisors are 1 and 10909. Therefore 10909 is a prime number.

As a consequence, 10909 is only a multiple of 1 and 10909.

Since 10909 is a prime number, 10909 is also a deficient number, that is to say 10909 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 10909 without 10909 itself (that is 1, by definition!).

## Parity of 10909

10909 is an odd number, because it is not evenly divisible by 2.

## Is 10909 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 10909 is about 104.446.

Thus, the square root of 10909 is not an integer, and therefore 10909 is not a square number.

Anyway, 10909 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 10909?

The square of a number (here 10909) is the result of the product of this number (10909) by itself (i.e., 10909 × 10909); the square of 10909 is sometimes called "raising 10909 to the power 2", or "10909 squared".

The square of 10909 is 119 006 281 because 10909 × 10909 = 109092 = 119 006 281.

As a consequence, 10909 is the square root of 119 006 281.

## Number of digits of 10909

10909 is a number with 5 digits.

## What are the multiples of 10909?
