Is 11887 a prime number? What are the divisors of 11887?

## Is 11887 a prime number?

Yes, 11887 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 11887, the only two divisors are 1 and 11887. Therefore 11887 is a prime number.

As a consequence, 11887 is only a multiple of 1 and 11887.

Since 11887 is a prime number, 11887 is also a deficient number, that is to say 11887 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11887 without 11887 itself (that is 1, by definition!).

## Parity of 11887

11887 is an odd number, because it is not evenly divisible by 2.

## Is 11887 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 11887 is about 109.028.

Thus, the square root of 11887 is not an integer, and therefore 11887 is not a square number.

Anyway, 11887 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11887?

The square of a number (here 11887) is the result of the product of this number (11887) by itself (i.e., 11887 × 11887); the square of 11887 is sometimes called "raising 11887 to the power 2", or "11887 squared".

The square of 11887 is 141 300 769 because 11887 × 11887 = 118872 = 141 300 769.

As a consequence, 11887 is the square root of 141 300 769.

## Number of digits of 11887
