Question

Smallest 4 digit number which is divisible by 16,20 and 30

Answer 1

To find it we have to find the LCM
=LCM of 16,20,30 is 240 so now we keep on multiply to get the four digit number we see first by 240.
=240x1=240
240x2=480
240x3=720
240x4=960
240x5=1200 is the smallest four digit we see which is divisible by 16,20 and 30.
