Is 11813 a prime number? What are the divisors of 11813?

## Is 11813 a prime number?

Yes, 11813 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 11813, the only two divisors are 1 and 11813. Therefore 11813 is a prime number.

As a consequence, 11813 is only a multiple of 1 and 11813.

Since 11813 is a prime number, 11813 is also a deficient number, that is to say 11813 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11813 without 11813 itself (that is 1, by definition!).

## Parity of 11813

11813 is an odd number, because it is not evenly divisible by 2.

## Is 11813 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 11813 is about 108.688.

Thus, the square root of 11813 is not an integer, and therefore 11813 is not a square number.

Anyway, 11813 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11813?

The square of a number (here 11813) is the result of the product of this number (11813) by itself (i.e., 11813 × 11813); the square of 11813 is sometimes called "raising 11813 to the power 2", or "11813 squared".

The square of 11813 is 139 546 969 because 11813 × 11813 = 118132 = 139 546 969.

As a consequence, 11813 is the square root of 139 546 969.

## Number of digits of 11813

11813 is a number with 5 digits.

## What are the multiples of 11813?
