Answer:
Basically, you have to find LCM OF 2, 14, 21. Here, I give you a short-cut method. However, you have to be good at numbers. Consider the greatest number 21. 2 can divide it. 14 cannot divide it. Take the next multiple of 21, that is 42. Now, all the three numbers can divide 42 evenly. Therefore, 42 is the least number, which can be divided by 2, 14, 21.
