Question
The product of the two prime numbers is 187. What will
the L.C.M of these two numbers?Solution
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 = 187 And we know that HCF for two prime numbers is = 1 So,  187 = LCM of (a, b) × 1 ⇒ LCM of (a, b) = 187
