Below you can check the types of numbers in Maths along with their definitions.

**Natural Numbers** – All positive or non-negative counting numbers. The set of natural numbers are commonly denoted as N.

Example – (1, 2, 3,4…..∞).

**Whole Numbers** – If we add zero in natural numbers set then it becomes whole numbers set.

Example – (0, 1, 2, 3,4…..∞).

**Integers** – Integers are all whole numbers which include negative numbers as well as positive numbers.

Example – (∞……-4,-3,-2,-1,0,1,2,3,4,5….∞).

**Even & Odd Numbers** – If the number is divided by 2 then it is called even number and if it is not then the numbers are called odd numbers.

Example – (0,2,4,6,8,10,12…..∞) are even numbers and (1,3,5,7,9,11,13,15,17,19….∞) are odd numbers.

**Prime Numbers** – If a number is divided by itself only then it is called prime number. Prime Numbers can be positive or negative except 1.

Example – (2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61….∞)

**Composite Numbers** – Natural numbers which are not prime are called composite numbers.

Example – (4,6,8,9,10,12,14,15,16,18,20,21,22,……….. ∞)

**Co-Prime Numbers** – Two natural number a and b are said to be co-prime if their HCF is 1.

In a simpler way, two integers (a and b) are coprime (or relatively prime) if they share no common factors. In other words, there is no number, other than 1, that divides both a and b evenly.

Example – 6 and 35 are coprime, because the factors of 6, 2 and 3, do not divide 35 evenly. 6 and 27 are not coprime, because 3 divides both 6 and 27.
