Question

0.5 What is the HCF of the smallest natural number and smallest prime number?​

Answer 1

Answer:

So according to the above definition, the smallest composite number is 4. A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers or only has two factors 1and the number itself. So, the smallest prime number is 2. HCF is the Highest common factor.

Answer 2

Answer:

The HCF of the smallest natural number and the smallest prime number is 1

Explanation:

Question:

What is the HCF of the smallest natural number and smallest prime number?

Given:

• Smallest natural number = 1
• Smallest prime number = 2

To find:

HCF(1,2)

Concept:

Prime factorization

Steps involved:

Step 1: Find the prime factorization of the smallest natural number(1)

The prime factorization of 1 is 1( the number itself)

Step 2: Find the prime factorization of the smallest prime number(2)

The prime factorization of 2 is 2 the number itself)

Step 3: To find the HCF, we need to multiply the common prime factors of the both numbers(1,2)

Here, the only common factor is 1. This implies that 1 and 2 are co-primes.

Final answer:

The HCF of the smallest natural number and the smallest prime number is 1
