Question

If p and q are two prime numbers, then what is their HCF?

Answer 1

It is given that p and q are two prime numbers; we have to find their HCF.

We know that the factors of any prime number are 1 and the prime number itself.

For example, let p = 2 and q = 3 

Thus, the factors are as follows

p = 2 × 1 

And

q = 3 × 1 

Now, the HCF of 2 and 3 is 1.

Thus the HCF of p and q is 1.
