HCF of smallest prime and smallest composite. number is

To find the HCF (Highest Common Factor) of the smallest prime and smallest composite number, we first need to determine what these numbers are.

The smallest prime number is 2, as it is the only prime number that is divisible only by 1 and itself.

The smallest composite number is 4, as it is the smallest number that is not prime and can be divided evenly by numbers other than 1 and itself.

Now, to find the HCF of 2 and 4, we need to list the factors of each number.

The factors of 2 are 1 and 2.

The factors of 4 are 1, 2, and 4.

To find the HCF, we need to identify the common factors of both numbers. In this case, the only common factor is 2.

Therefore, the HCF of the smallest prime (2) and the smallest composite (4) is 2.
