Is 2687 a prime number? What are the divisors of 2687?

## Is 2687 a prime number?

Yes, 2687 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 2687, the only two divisors are 1 and 2687. Therefore 2687 is a prime number.

As a consequence, 2687 is only a multiple of 1 and 2687.

Since 2687 is a prime number, 2687 is also a deficient number, that is to say 2687 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 2687 without 2687 itself (that is 1, by definition!).

## Parity of 2687

2687 is an odd number, because it is not evenly divisible by 2.

## Is 2687 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 2687 is about 51.836.

Thus, the square root of 2687 is not an integer, and therefore 2687 is not a square number.

Anyway, 2687 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 2687?

The square of a number (here 2687) is the result of the product of this number (2687) by itself (i.e., 2687 × 2687); the square of 2687 is sometimes called "raising 2687 to the power 2", or "2687 squared".

The square of 2687 is 7 219 969 because 2687 × 2687 = 26872 = 7 219 969.

As a consequence, 2687 is the square root of 7 219 969.

## Number of digits of 2687

2687 is a number with 4 digits.

## What are the multiples of 2687?

The multiples of 2687 are all integers evenly divisible by 2687, that is all numbers such that the remainder of the division by 2687 is zero. There are infinitely many multiples of 2687. The smallest multiples of 2687 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 2687 too, since 0 × 2687 = 0
• 2687: indeed, 2687 is a multiple of itself, since 2687 is evenly divisible by 2687 (we have 2687 / 2687 = 1, so the remainder of this division is indeed zero)
• 5 374: indeed, 5 374 = 2687 × 2
• 8 061: indeed, 8 061 = 2687 × 3
• 10 748: indeed, 10 748 = 2687 × 4
• 13 435: indeed, 13 435 = 2687 × 5
• etc.
