Is 2909 a prime number? What are the divisors of 2909?

## Is 2909 a prime number?

Yes, 2909 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 2909, the only two divisors are 1 and 2909. Therefore 2909 is a prime number.

As a consequence, 2909 is only a multiple of 1 and 2909.

Since 2909 is a prime number, 2909 is also a deficient number, that is to say 2909 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 2909 without 2909 itself (that is 1, by definition!).

## Parity of 2909

2909 is an odd number, because it is not evenly divisible by 2.

## Is 2909 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 2909 is about 53.935.

Thus, the square root of 2909 is not an integer, and therefore 2909 is not a square number.

Anyway, 2909 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 2909?

The square of a number (here 2909) is the result of the product of this number (2909) by itself (i.e., 2909 × 2909); the square of 2909 is sometimes called "raising 2909 to the power 2", or "2909 squared".

The square of 2909 is 8 462 281 because 2909 × 2909 = 29092 = 8 462 281.

As a consequence, 2909 is the square root of 8 462 281.

## Number of digits of 2909

2909 is a number with 4 digits.

## What are the multiples of 2909?

The multiples of 2909 are all integers evenly divisible by 2909, that is all numbers such that the remainder of the division by 2909 is zero. There are infinitely many multiples of 2909. The smallest multiples of 2909 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 2909 too, since 0 × 2909 = 0
• 2909: indeed, 2909 is a multiple of itself, since 2909 is evenly divisible by 2909 (we have 2909 / 2909 = 1, so the remainder of this division is indeed zero)
• 5 818: indeed, 5 818 = 2909 × 2
• 8 727: indeed, 8 727 = 2909 × 3
• 11 636: indeed, 11 636 = 2909 × 4
• 14 545: indeed, 14 545 = 2909 × 5
• etc.
