Is 9491 a prime number? What are the divisors of 9491?

Is 9491 a prime number?

Yes, 9491 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 9491, the only two divisors are 1 and 9491. Therefore 9491 is a prime number.

As a consequence, 9491 is only a multiple of 1 and 9491.

Since 9491 is a prime number, 9491 is also a deficient number, that is to say 9491 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 9491 without 9491 itself (that is 1, by definition!).

Parity of 9491

9491 is an odd number, because it is not evenly divisible by 2.

Is 9491 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 9491 is about 97.422.

Thus, the square root of 9491 is not an integer, and therefore 9491 is not a square number.

Anyway, 9491 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 9491?

The square of a number (here 9491) is the result of the product of this number (9491) by itself (i.e., 9491 × 9491); the square of 9491 is sometimes called "raising 9491 to the power 2", or "9491 squared".

The square of 9491 is 90 079 081 because 9491 × 9491 = 94912 = 90 079 081.

As a consequence, 9491 is the square root of 90 079 081.
