LCM and HCF of two numbers are 90 and 15, respectively. If the sum of the two numbers is 75, then find the greater number.
Answer & explanation
Correct answer: option 2
Product of two prime factors = \(\frac{LCM}{HCF}\) = \(\frac{90}{15}\) = 6
Prime factor are = 2 & 3
Greater number = 3 × HCF = 3 × 15 = 45
