LCM of two prime numbers is ________________.

• A. product of both numbers
• B. sum of two numbers
• C. difference of both the numbers
• D. division of both the numbers

Answer 1

The correct option is A

product of both numbers

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
