What is a Hilbert Number

A Hilbert number is a positive integer that can be represented in the form of 4k + 1, where k is a non-negative integer. In other words, Hilbert numbers are those integers that can be expressed as 1, 5, 9, 13, 17, and so on. They belong to a specific sequence of numbers that possess intriguing mathematical properties.

How to Check for Hilbert Numbers

Checking whether a number is a Hilbert number is a straightforward process. Let’s go through the step-by-step method to determine if a given number falls into this category:

Begin with the number you want to check.
Subtract 1 from the number.
Divide the resulting value by 4.
If the division yields an integer without any remainder, the number is a Hilbert number.
If there is a remainder, the number does not belong to the Hilbert sequence.

For example, Let’s check whether the number 17 is a Hilbert number.

Begin with the number you want to check: 17.

Subtract 1 from the number:

17 – 1 = 16

Divide the resulting value by 4:

16 / 4 = 4

The division yields an integer without any remainder.

So, the number 17 is a Hilbert number.

FAQS

Q1: How can I determine if a number is a Hilbert number?
A: To check if a number x is a Hilbert number, subtract 1 from x and divide the result by 4. If the division yields an integer without any remainder, then x is a Hilbert number.

Q2: Are negative numbers considered Hilbert numbers?
A: No, Hilbert numbers are defined as positive integers.

Q3: Can decimals or fractions be Hilbert numbers?
A: No, Hilbert numbers are whole numbers only.

Q4: What are the main properties of Hilbert numbers?
A: Hilbert numbers have interesting connections to the Hilbert class field and certain quadratic fields.

Q5: What is the significance of Hilbert numbers?
A: Hilbert numbers are important in number theory and have various applications, particularly in the study of quadratic residues and modular arithmetic.

Q6: Are all prime numbers Hilbert numbers?
A: No, not all prime numbers are Hilbert numbers. Hilbert numbers are a specific subset of integers, and prime numbers can have different forms and properties.
