LCM of two prime numbers is ________________.


Options:
A .   product of both numbers
B .   sum of two numbers
C .   difference of both the numbers
D .   division of both the numbers
Answer: Option A
:
A

Prime numbers have only two factors 1 and the number itself.
Hence, LCM of two prime numbers is always the product of the two numbers.


For example, LCM of 3 and 5 = 3 × 5 = 15
Similarly, LCM of 7 and 11 = 7 × 11 = 77
