Is 59 a prime number? What are the divisors of 59?

Is 59 a prime number?

It is possible to find out using mathematical methods whether a given integer is a prime number or not.

For 59, the answer is: yes, 59 is a prime number because it has only two distinct divisors: 1 and itself (59).

As a consequence, 59 is only a multiple of 1 and 59..

Since 59 is a prime number, 59 is also a deficient number, that is to say 59 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 59 without 59 itself (that is 1, by definition!).

Parity of 59

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

Is 59 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 59 is about 7.681.

Thus, the square root of 59 is not an integer, and therefore 59 is not a square number.

Anyway, 59 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 59?

The square of a number (here 59) is the result of the product of this number (59) by itself (i.e., 59 × 59); the square of 59 is sometimes called "raising 59 to the power 2", or "59 squared".

The square of 59 is 3 481 because 59 × 59 = 592 = 3 481.

As a consequence, 59 is the square root of 3 481.

Number of digits of 59

59 is a number with 2 digits.

What are the multiples of 59?

The multiples of 59 are all integers evenly divisible by 59, that is all numbers such that the remainder of the division by 59 is zero. There are infinitely many multiples of 59. The smallest multiples of 59 are:

  • 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 59 too, since 0 × 59 = 0
  • 59: indeed, 59 is a multiple of itself, since 59 is evenly divisible by 59 (we have 59 / 59 = 1, so the remainder of this division is indeed zero)
  • 118: indeed, 118 = 59 × 2
  • 177: indeed, 177 = 59 × 3
  • 236: indeed, 236 = 59 × 4
  • 295: indeed, 295 = 59 × 5
  • etc.

How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 59). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 7.681). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
