WebWhat is the Least Common Multiple (LCM) of 21 and 100? If you are searching to find out what the lowest common multiple of 21 and 100 is then you probably figured out you are in the right place! That's exactly what this quick guide is all about. We'll walk you through how to calculate the least common multiple for any numbers you need to check. Web42 ÷ 2 = 21. Now, check whether 21 can be further divided by 2 or not. 21 ÷ 2 = 10.5 But, a factor cannot be a fraction. Therefore, we will proceed to the next prime number, which is 3. Now, dividing 21 by 3 we get, 21 ÷ 3 = 7. Again, dividing 7 by 3 will give a fraction number. Therefore, taking the next prime number, 5, into consideration.
