Question

The least natural number is ______?

Answer 1

Hint: Natural numbers are the numbers which are positive integers and include numbers from \[1\] to infinity. Natural numbers do not consider negative numbers and zero. All the sets of natural numbers are denoted by \[''N''\]. \[N=\left\{ 1,2,3,4,5,6,7,8,9,10,11,12,......... \right\}\].

Complete step-by-step answer:
From the question it is clear that we have to find the least natural number.
From the basic concepts of mathematics, natural numbers are a part of a number system which includes all the positive integers till infinity. These are also called counting numbers.
Natural numbers are part of real numbers.
Zero, negative numbers, rational numbers, irrational numbers, decimal numbers, complex numbers are not considered as natural numbers.
Natural numbers are denoted by \[''N''\]
\[N=\left\{ 1,2,3,4,5,6,7,8,9,10,11,12,......... \right\}\]
So, numbers starting from 1 are considered as natural numbers.
Since it is not possible to write the greatest number because natural numbers go up to infinity, we can only write the least number.
In the set of \[N=\left\{ 1,2,3,4,5,6,7,8,9,10,11,12,......... \right\}\], we can clearly see that\[1\] is the starting number and small number.
\[1\] is a positive integer and we cannot write a positive integer less than \[1\].
So now we can conclude that \[1\] is the least natural number.

Note: This question is completely based on concept. Students should know the basic concepts of the number system. Students may have the misconception that zero is also included in the set of natural numbers but actually natural numbers including zero are considered as whole numbers. here we need only natural numbers so, here we will not consider zero.
