Is 9439 a prime number? What are the divisors of 9439?

## Is 9439 a prime number?

Yes, 9439 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 9439, the only two divisors are 1 and 9439. Therefore 9439 is a prime number.

As a consequence, 9439 is only a multiple of 1 and 9439.

Since 9439 is a prime number, 9439 is also a deficient number, that is to say 9439 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 9439 without 9439 itself (that is 1, by definition!).

## Parity of 9439

9439 is an odd number, because it is not evenly divisible by 2.

## Is 9439 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 9439 is about 97.155.

Thus, the square root of 9439 is not an integer, and therefore 9439 is not a square number.

Anyway, 9439 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 9439?

The square of a number (here 9439) is the result of the product of this number (9439) by itself (i.e., 9439 × 9439); the square of 9439 is sometimes called "raising 9439 to the power 2", or "9439 squared".

The square of 9439 is 89 094 721 because 9439 × 9439 = 94392 = 89 094 721.

As a consequence, 9439 is the square root of 89 094 721.

## Number of digits of 9439

9439 is a number with 4 digits.

## What are the multiples of 9439?

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 9439 too, since 0 × 9439 = 0
• 9439: indeed, 9439 is a multiple of itself, since 9439 is evenly divisible by 9439 (we have 9439 / 9439 = 1, so the remainder of this division is indeed zero)
• 18 878: indeed, 18 878 = 9439 × 2
• 28 317: indeed, 28 317 = 9439 × 3
• 37 756: indeed, 37 756 = 9439 × 4
• 47 195: indeed, 47 195 = 9439 × 5
• etc.
