What is the HCF of the smallest prime number and the smallest composite number?
Ans. Prime number – A number which has exactly two factors is called Prime Number. i.e. it can be divided by only the number ‘1’ and itself.
The smallest prime number is = 2
Composite number – A composite number has more than two factors. Examples: “6” the factors of “6” are 1,2,3 and 6 itself. So, it is called a composite number.
The smallest composite number is = 4
2 is the factor of 4
∴ H.C.F of the smallest prime number and the smallest composite number is 2
