Is 15187 a prime number? What are the divisors of 15187?

Is 15187 a prime number?

Yes, 15187 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 15187, the only two divisors are 1 and 15187. Therefore 15187 is a prime number.

As a consequence, 15187 is only a multiple of 1 and 15187.

Since 15187 is a prime number, 15187 is also a deficient number, that is to say 15187 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 15187 without 15187 itself (that is 1, by definition!).

Parity of 15187

15187 is an odd number, because it is not evenly divisible by 2.

Is 15187 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 15187 is about 123.236.

Thus, the square root of 15187 is not an integer, and therefore 15187 is not a square number.

Anyway, 15187 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 15187?
