= 2*2
5 = 5*1
6 = 2 * 3
LCM = 2*2*5*3 = 60
The first number after two hundred is 240 and the last number is 600. All you need do is list them.
240
300
360
420
480

We will take the LCM of 4,5,6 which is 60.now if any number is multiple of 60 then the condition is satisfied.nearest to 200 , 240 is the first number divisible by 60. a+(n-1)d = Tn a=240 , d = 60 , Tn = 600 240+(n-1)60 = 600 n= 7that means there are 7 numbers divisible by 4,5,6
