Question

Fill in the blank:-
The only even prime number is __________

Answer 1

Hint: Before solving this question, we must know about Prime Numbers.
PRIME NUMBERS: Prime numbers are whole numbers that are greater than 1, that have only two factors:- 1 and the number itself.
Prime numbers are divisible only by the number 1 or itself.
For example: 2, 3, 5, 7, 11, etc.

Complete step-by-step solution -
The only even number that is a prime number, or we can say that the only prime number that is an even number is the number 2.
This is a fact that the number 2 is not divisible by any number other than 1 and 2.
Therefore, two is the only even prime number.
Hence, the answer of this question is two. In other words, we can say that the word that will fill the blank is 2.

Note:- We must know that 1 is neither a prime number, nor a composite number.
Let us now learn about composite numbers.
COMPOSITE NUMBERS: The whole numbers that have more than two factors are called composite numbers.
Whole numbers that are not prime numbers are composite numbers, because they are divisible by more than two numbers.
