Is 8209 a prime number? What are the divisors of 8209?

Is 8209 a prime number?

Yes, 8209 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 8209, the only two divisors are 1 and 8209. Therefore 8209 is a prime number.

As a consequence, 8209 is only a multiple of 1 and 8209.

Since 8209 is a prime number, 8209 is also a deficient number, that is to say 8209 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 8209 without 8209 itself (that is 1, by definition!).

Parity of 8209

8209 is an odd number, because it is not evenly divisible by 2.

Is 8209 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 8209 is about 90.604.

Thus, the square root of 8209 is not an integer, and therefore 8209 is not a square number.

Anyway, 8209 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 8209?

The square of a number (here 8209) is the result of the product of this number (8209) by itself (i.e., 8209 × 8209); the square of 8209 is sometimes called "raising 8209 to the power 2", or "8209 squared".

The square of 8209 is 67 387 681 because 8209 × 8209 = 82092 = 67 387 681.

As a consequence, 8209 is the square root of 67 387 681.

Number of digits of 8209

8209 is a number with 4 digits.

What are the multiples of 8209?

The multiples of 8209 are all integers evenly divisible by 8209, that is all numbers such that the remainder of the division by 8209 is zero. There are infinitely many multiples of 8209. The smallest multiples of 8209 are:

  • 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 8209 too, since 0 × 8209 = 0
  • 8209: indeed, 8209 is a multiple of itself, since 8209 is evenly divisible by 8209 (we have 8209 / 8209 = 1, so the remainder of this division is indeed zero)
  • 16 418: indeed, 16 418 = 8209 × 2
  • 24 627: indeed, 24 627 = 8209 × 3
  • 32 836: indeed, 32 836 = 8209 × 4
  • 41 045: indeed, 41 045 = 8209 × 5
  • etc.
