Is 2609 a prime number? What are the divisors of 2609?

## Is 2609 a prime number?

Yes, 2609 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 2609, the only two divisors are 1 and 2609. Therefore 2609 is a prime number.

As a consequence, 2609 is only a multiple of 1 and 2609.

Since 2609 is a prime number, 2609 is also a deficient number, that is to say 2609 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 2609 without 2609 itself (that is 1, by definition!).

## Parity of 2609

2609 is an odd number, because it is not evenly divisible by 2.

## Is 2609 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 2609 is about 51.078.

Thus, the square root of 2609 is not an integer, and therefore 2609 is not a square number.

Anyway, 2609 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 2609?

The square of a number (here 2609) is the result of the product of this number (2609) by itself (i.e., 2609 × 2609); the square of 2609 is sometimes called "raising 2609 to the power 2", or "2609 squared".

The square of 2609 is 6 806 881 because 2609 × 2609 = 26092 = 6 806 881.

As a consequence, 2609 is the square root of 6 806 881.

## Number of digits of 2609

2609 is a number with 4 digits.

## What are the multiples of 2609?

The multiples of 2609 are all integers evenly divisible by 2609, that is all numbers such that the remainder of the division by 2609 is zero. There are infinitely many multiples of 2609. The smallest multiples of 2609 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 2609 too, since 0 × 2609 = 0
• 2609: indeed, 2609 is a multiple of itself, since 2609 is evenly divisible by 2609 (we have 2609 / 2609 = 1, so the remainder of this division is indeed zero)
• 5 218: indeed, 5 218 = 2609 × 2
• 7 827: indeed, 7 827 = 2609 × 3
• 10 436: indeed, 10 436 = 2609 × 4
• 13 045: indeed, 13 045 = 2609 × 5
• etc.
