The product of the two prime numbers is 493. What will the L.C.M of these two numbers?
Correct Answer: Option A
We know that,
If there are two numbers a and b,
Then, a × b = LCM of (a, b) × HCF of (a, b)
According to the question a × b = 493
And we know that HCF for two prime numbers is = 1
So, 493 = LCM of (a, b) × 1
⇒ LCM of (a, b) = 493
Hint: L.C.M. of some prime numbers is always the product of those numbers.
