प्रश्न
If p and q are two prime number, then what is their LCM?
उत्तर
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 = 2xx1`
And
`q= 3xx1`
Now, the LCM of 2 and 3 is `2xx3 =6` .
Thus the HCF of p and q is `pxxq`.
