In Question, it is asking the next largest number that is divisible by all the three given numbers.
so to get the next number you have to add the LCM to number K. Because K can be anything ... if it is 390 then as per 2k answer next number will be 390*2 = 780
but as per k+130 option it will be 390+130 = 520, which will be next number.
I hope you got the reason for it.
