Types of Odd Numbers

Various types of Odd Numbers are as follows,

  • Consecutive Odd Numbers
  • Composite Odd Numbers
  • Prime Odd Numbers

Now let’s learn about them in detail.

Consecutive Odd Numbers

For any number to be consecutive, they need to follow each other in order, and if numbers are consecutive as well as Odd in nature then those are called consecutive odd numbers. Examples of consecutive odd numbers include 1, 3, 5, 7, and 9 (the first five consecutive odd natural numbers), and 11, 13, 15, 17, and 19. If we have an odd number a, we can determine the next consecutive odd number by adding 2 to it, i.e., a+2. It is important to note that the difference between any two consecutive odd or even numbers is always 2.

Composite Odd Numbers

Positive integers that have factors other than 1 and themselves are called composite numbers. For a number to be considered a composite odd number, a number must be both odd and composite. For instance, 9 is a composite odd number because it is divisible by 3, and when divided by 2, it gives a remainder of 1. Other examples of composite odd numbers include 15, 27, 35, 65, and so on.

Prime Odd Numbers

Except for the number 2, all prime numbers are odd. This is because, except for 2, all even numbers have 2 as a factor, making them composite numbers. However, not all odd numbers are prime since the product of two odd numbers is also an odd number, but it cannot be a prime number because it has two factors. A prime number is defined as an odd number that has no factors other than 1 and itself.

Some examples of prime as well as odd numbers are 3, 5, 7, 11, 13, 17, 19, etc.

Note: All Prime Numbers are Odd Numbers except for 2 which is Even Number

Smallest Odd Number

The smallest odd number is 1 as is the smallest number in the lot of odd number. Other odd number are, 1, 3, 5, 7, 9,…

First 10 Odd Numbers

The first 10 odd numbers are,

1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.

Odd Prime Numbers

All the prime number except for 2 are odd numbers because all even numbers have at least one factor that is 2. Various odd prime numbers are,

1, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc.

Odd Natural Numbers

Natural Numbers are the number that are used for counting numbers. Various odd natural number are,

1, 3, 5, 7, 9,…

Odd Numbers 1 to 100

Odd numbers 1 to 100 in maths are numbers that are divided by two resulting in the remainder as one. Suppose we are given a number and its division by two results one as the remainder then it is an odd number.

For identifying odd numbers the trick is that the ones digit of the odd number is always 1, 3, 5, 7, and 9. For example, 91, 45, 77, 3, etc all are odd numbers. Odd numbers can also be negative and their examples are, -61, -13, -27, etc.

In this article, we will learn about what are odd numbers, a list of odd numbers 1 to 100, and examples of odd numbers in detail.

What are Odd Numbers?

For any number when divided by 2, if the reminder is non zero i.e. 1 then it is an Odd Number. In other words, a number is an Odd number if it is not divisible by 2. For example, 1, 3, 5, 7, 9, etc. One intuitive way to understand Odd numbers is to assume you have n number of fruits, if you try to divide those n fruits among two people such that one person ends up with one more fruit than the other person, then you have an odd number of fruits in the beginning....
