1) Product, of two co-prime numbers is 117. Their L.C.M. should be : A) 1 B) 117 C) Equal to their H.C.F D) 235 E) Cannot be calculated Answer: Option BExplanation:H.C.F of co-prime numbers is 1. So, L.C.M = (117/1) = 117 Note: In number theory, two integers a and b are said to be co-prime, if the only positive integer that divides both of them is 1.
