Is 8243 a prime number? What are the divisors of 8243?

Is 8243 a prime number?

Yes, 8243 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 8243, the only two divisors are 1 and 8243. Therefore 8243 is a prime number.

As a consequence, 8243 is only a multiple of 1 and 8243.

Since 8243 is a prime number, 8243 is also a deficient number, that is to say 8243 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 8243 without 8243 itself (that is 1, by definition!).

Parity of 8243

8243 is an odd number, because it is not evenly divisible by 2.

Is 8243 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 8243 is about 90.791.

Thus, the square root of 8243 is not an integer, and therefore 8243 is not a square number.

Anyway, 8243 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 8243?

The square of a number (here 8243) is the result of the product of this number (8243) by itself (i.e., 8243 × 8243); the square of 8243 is sometimes called "raising 8243 to the power 2", or "8243 squared".

The square of 8243 is 67 947 049 because 8243 × 8243 = 82432 = 67 947 049.

As a consequence, 8243 is the square root of 67 947 049.
