Concept: Prime numbers are so-called because they contain all-natural numbers with just two factors, which are the number itself and the number 1.
Before we can answer the question, we must first recall the many sorts of numbers and their various categories. By definition, we can state that choice C is the correct response.. Examples of prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, and so on up to infinity.
To answer the question, we must first know all of the following definitions for the various sorts of numbers and the major categories of numbers:
Natural numbers are all positive numbers with a denominator of 1 and either no decimal part or a decimal part of zero. Natural numbers include, for instance, 1, 2, 3, 4, 5, 6, and.
Whole numbers are all non-negative numbers with a denominator of 1 and either no decimal component or zero decimal part (0 is neither a positive nor a negative number ) . We can also assert that all natural numbers greater than zero are whole numbers.
All non-positive and non-negative numbers with a denominator of 1 and either no decimal component or zero decimal part are considered integers. Integers include, for instance, 5, 4, 3, 2, 1, 0, 1, 2, 3, 4, 5, and so on.
Prime numbers are all numbers with just two components: the number itself and the number one. Prime numbers include, for instance, 2, 3, 5, 7, 11, 13, 17, 19, and so forth.
All numbers that have more than two variables, or more specifically, all numbers that have factors besides themselves and number 1, are considered composite numbers. In other terms, we can state that the number 1 must be excluded along with any non-prime numbers.
All integers that are exactly not divisible by two or, when divided by two, have a result in decimal or fraction form are considered odd numbers. For instance, odd numbers include 5, 3, 1, 3, 5, 7, 9, etc.
All integers that are exactly divisible by two are considered even numbers. As an illustration, even numbers include 4, 2, 0, 2, 4, 6, 8, 10, and so on.
Therefore, by examining the definitions that must be memorised, we can conclude that the definition of the prime number is the response to our query about the category of numbers in which the numbers have just two factors, one of which is number 1 and the other is the number itself.
Hence, the correct answer is option (3) .
