Is 31573 a prime number? What are the divisors of 31573?

Is 31573 a prime number?

Yes, 31573 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 31573, the only two divisors are 1 and 31573. Therefore 31573 is a prime number.

As a consequence, 31573 is only a multiple of 1 and 31573.

Since 31573 is a prime number, 31573 is also a deficient number, that is to say 31573 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 31573 without 31573 itself (that is 1, by definition!).

Parity of 31573

31573 is an odd number, because it is not evenly divisible by 2.

Is 31573 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 31573 is about 177.688.

Thus, the square root of 31573 is not an integer, and therefore 31573 is not a square number.

Anyway, 31573 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 31573?
