Values b and c are not properly arranged within a sequence, but since requirements ask for min and max this code completes a job: I saw this answer that used for loop and if else decision statement , however I will post a solution that I suppose will run faster and will use only four variables. Can I move my D drive to a "D" partition on my C drive? Why is the 'auto' keyword useful for compiler writers in C? It may be the same but they come under different classification in C ."? -- Since this question was asked before loops, arrays and functions were covered in the book, I am assuming that these should not be used. Please Enter three Numbers: 98 11 129 11 is Lesser Than both 98 and 129 In this Java smallest of three numbers example, we used the ternary operator twice. This is much much faster and easier than prime factoring. Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, The future of collective knowledge sharing, Yes, I am aware of using conditional expressions would solve this with, While I don't know if it helps (I haven't really given it much through) but if. Does one need to buy tickets in advance for Deutsche Bahn train? As has been expressed in other answers to this problem, the critical insight is that, $$LCM(1..1) = 1$$ Sorry. We must note that negative integers and zero aren't candidates for LCM. Has anyone tried to make 3-D chess in real life? User-defined Exceptions for Stack implementation. Overview The Least Common Multiple (LCM) of two non-zero integers (a, b) is the smallest positive integer that is perfectly divisible by both a and b. Chicken and egg problem with NTP and Bind. These are all comparison sorts, and so cannot perform better than O(n log n) in the average or worst case" (source), so I think this shouldn't be too far off in terms of minimum number of ifs.. For example, if you know that a > b is true, from that single comparison you should realize that a is no longer candidate for the smallest and should no longer participate in any comparisons dedicated to finding the smallest.
