Q. Product of two co-prime numbers is 117. Then their LCM is = ?
β
Correct Answer: (A)
117
Explanation: HCF of co-prime number is always 1
∴ Let number are = x & y respectively
Product of number = xy
xy = 117 (given)
∴ Product of number = LCM × HCF
⇒ LCM × 1 = 117
⇒ LCM = 117
∴ Let number are = x & y respectively
Product of number = xy
xy = 117 (given)
∴ Product of number = LCM × HCF
⇒ LCM × 1 = 117
⇒ LCM = 117
