The product of two co-prime numbers is 117. Their LCM should be:
Answer: B
Co-prime numbers are numbers whose Highest Common Factor (HCF) is 1.
We know that for any two numbers a and b, Product of numbers = HCF(a,b) × LCM(a,b).
Given, Product = 117 and HCF = 1 (since they are co-prime).
117 = 1 × LCM.
Therefore, LCM = 117.
