Question

if p and q are two prime numbers than what is their hcf

Answer 1

Factors of p= 1, p
Factors of q= 1, q
Thus their hcf will be 1.

Answer 2

Answer:

The “common factor” of p and q is one.

Solution:

HCF: The full form of HCF is “Highest Common Factor”.

The largest common factor of two or more natural numbers is called as “highest common factor”.

HCF is also known as “greatest common Divisor (GCD)”.

Given that  

P and q are two prime numbers

The HCF of two p and q prime numbers is one and itself.

Here the “common factor” is 1.

Therefore, the “common factor” of p and q is one.
