Question

the HCF of least prime number and least composite number is

Answer 1

the least prime no is 2
the least composite no is 4
hcf(2,4)=2

(note: 1 is neither prime nor composite)

Answer 2

The given question is the HCF of the least prime number and least composite number.

The solution to this problem is we have to find the HCF of the least prime number and the least composite number.

Firstly, the HCF stands for Highest Common Factor.

where HCF of two integers is the smallest factor, that divides both the integers.

Secondly, the prime number is a number whose factor is 1 and a number itself.

and the composite number is a number which is other than a prime number.

1 is neither a prime nor a composite number as it divides both the prime and composite numbers.

The least prime number is 2 and the least composite number is 4.

we have to find the HCF of these two factors, this can be obtained by a prime factorisation method.

$2)2 \: \: \: 4 \\ )1 \: \: \: \: 2$

where the factors of these two were 2*2 on taking only one 2 as the factor.

Therefore, the final answer is the HCF of the least prime number and the least composite number is 2.
