Question

The product of the two prime numbers is 187. What will the L.C.M of these two numbers?

A 187 Correct Answer Incorrect Answer
B 107 Correct Answer Incorrect Answer
C 197 Correct Answer Incorrect Answer
D 177 Correct Answer Incorrect Answer

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
