Is 11243 a prime number? What are the divisors of 11243?

## Is 11243 a prime number?

Yes, 11243 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 11243, the only two divisors are 1 and 11243. Therefore 11243 is a prime number.

As a consequence, 11243 is only a multiple of 1 and 11243.

Since 11243 is a prime number, 11243 is also a deficient number, that is to say 11243 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11243 without 11243 itself (that is 1, by definition!).

## Parity of 11243

11243 is an odd number, because it is not evenly divisible by 2.

## Is 11243 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 11243 is about 106.033.

Thus, the square root of 11243 is not an integer, and therefore 11243 is not a square number.

Anyway, 11243 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11243?

The square of a number (here 11243) is the result of the product of this number (11243) by itself (i.e., 11243 × 11243); the square of 11243 is sometimes called "raising 11243 to the power 2", or "11243 squared".

The square of 11243 is 126 405 049 because 11243 × 11243 = 112432 = 126 405 049.

As a consequence, 11243 is the square root of 126 405 049.

## Number of digits of 11243
