if p and q are two prime number, then what is their LCM?
It is given that p and q are two prime numbers; we have to find their LCM.
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
$p=2 \times 1$
$q=3 \times 1$
Now, the LCM of 2 and 3 is $2 \times 3=6$.
Thus the HCF of $p$ and $q$ is $p \times q$.
