Product of two co-prime numbers is 117. Then their LCM is :
Product of two co-prime numbers is 117. Then their LCM is :
[A]9
[B]13
[C]39
[D]117
117
HCF of two prime numbers = 1
∴ Product of numbers = 117 (Their LCM)
117 = 13 $latex \times$ 9 where 13 & 9 are co-prime.
LCM (13, 9) = 117.
Hence option [D] is correct answer.
