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......
