Solution for Quant Question of the day: 255
We will take 3 smallest prime numbers to start that are 2,3,5
now we will pick 2 at a time from the above list and multiply them. It will be 3C2 ways = 3 ways
2*3 3*5 2*5
Now these 3 numbers are not co-prime and also none of them is multiple of other.
Hence 3 smallest prime will satisfy the requirement.
And Since these are the only prime in the list of numbers, hence their LCM will be 2*3*5 = 30
