Celtel is having a competition for it cellphone subscribers.It is giving away $1000 for every 100th caller,a cellphone to every 50th caller and a shopping voucher to every 30th caler.Which caller will receive all three prizes?
-----
Find the least common multiple of 100, 50, and 30.
-----
100 = 2^2*5*2
50 = 2*5^2
30 = 2*3*5
------
least common multiple = 2^2*5^2*3 = 4*25*3 = 300
-----
The 300th caller will get all three.
