Question

Is the LCM of two prime numbers same as their product?

• A. Yes
• B. No
• C. Cannot be determined

Answer 1

The correct option is A Yes

To find LCM, We write prime factorization of the numbers and calculate the LCM by multiplying the highest degree of prime numbers that are common in the prime factorization.

Let us assume two prime numbers $7$ and $11.$
Prime factorisation of $7$ and $11:$
$7=7\times 1$
$11=11\times 1$

To find LCM of $7$ and $11,$ we have to cover each factor in such a way that there is no repetition of factors.
$\text{LCM}(7,11)=7\times 11=77$
Therefore, LCM of two prime numbers is equal to their product.
