a smallest  positive number which is divisible by 4,5,6 is lcm of these numbers which is 60 ,


now if any number is multiple of 60 then the condition is satisfied ...


nearest to 200 , 240 is the first number  ....


now , a+(n-1)d = Tn


   a=240 , d = 60 , Tn = 600


     240+(n-1)60 = 600


     n= 7


that means there are 7 numbers......
