Natural numbers natural numbers starts from 1, 2,3,4… and goes till infinity.
Whole numbers Whole numbers starts from 0,2,3,4,……and goes till infinity.
composite number Composite numbers include numbers who comes in there own table, in the table of 1 and any other table they can come.
Example 4,6,8,9,12….
prime numbers Prime numbers include numbers who only comes in there own table or in the table of 1.
Example 1,2,3,5,7,….

Numbers are the basic unit of life. We can’t imagine our life without numbers. It influences our daily routine. In fact, our whole life is dependent on these numbers. Dates, year, time, mobile number, money, etc.
There are different types of numbers that are basically important in one’s life. Eg: Integer, whole numbers, natural numbers, rational numbers, etc.
On coming on to your question:
Prime Numbers: Prime numbers are the numbers that are divisible by 1 and themselves. In simple words, the prime numbers consist of those natural numbers which have exactly two factors and i.e. 1 and the number itself.
For eg:
2,3,5,7,11,13,17 etc.
All these numbers are divisible by 1 and the number itself.
Natural Numbers: All the positive numbers that are represented on the positive line of a number scale are called Natural Numbers. It doesn’t include zero.
For eg:
1,2,3,4,5,6,……. infinity.
Composite Numbers: <strong style=”fontfamily: inherit; fontsize: inherit;”>Composite numbers are those natural numbers that have more than two factors. Simply put, they are divisible by other numbers as well. Every nonprime number comes under the composite number.
For eg:
4,8,12,9,400 etc.
Whole Numbers: Natural Numbers including zero are called whole numbers.
For eg:
0,1,2,3,…….. infinity.

Prime numbers –
Any number that is divisible by 1 and itself, i.e., it cannot be divided using any number other than 1 and itself is known as a prime number.
for example 17, 23, 29 etc.
Natural Numbers
All the positive integers, for example – 1, 2, 3….infinity, excluding zero are known as natural numbers.
Composite numbers –
A composite number is a number that has at least one divisor other than 1 and itself. It is formed by multiplying two positive integers. For example – 2*3=6, where 6 is a composite number.
2*4=8, where 8 is a composite number.
Whole Numbers –
Any positive number, including zero, comes under the category of whole numbers.
for example – 0, 1, 2 , 3………infinity
