Oh I just read it again, and you wanted to calculate the next number greater than the LCM, lol I am sorry I will check that out too
Sure FlyingEagle, there is only one way I know of finding out the LCM:
1,2,3,4,5,6,7,8,9 - Divide them by each digit, one by one, until only 1 is left in the list.
First let us divide them by
2 (save this 2 on one side, to calculate the LCM), and the result is (Do not touch those that are not divisible):
2 |
1,2,3,4,5,6,7,8,9 = 1,1,3,2,5,3,7,4,9
Repeat the process till there is nothing but 1 is left in the list.
2 |
1,1,3,2,5,3,7,4,9 = 1,1,3,1,5,3,7,2,9
2 |
1,1,3,1,5,3,7,2,9= 1,1,3,1,5,3,7,1,9
2's multiples are gone, now similarly start with three:
3 |
1,1,3,1,5,3,7,1,9 = 1,1,1,1,5,1,7,1,3
3 |
1,1,1,1,5,1,7,1,3 = 1,1,1,1,5,1,7,1,1
Now 3's Multiples are gone, so start with 5:
5 |
1,1,1,1,5,1,7,1,1 = 1,1,1,1,1,1,7,1,1
Now 5's multiples are gone, start with 7:
7 |
1,1,1,1,1,1,7,1,1 = 1,1,1,1,1,1,1,1,1
Now, since we have divided it completely to get 1, multiply all the divosors ( marked in Red Color) and you will get the answer:
2 x 2 x 2 x 3 x 3 x 5 x 7 = 2520
Disregard if any calculation mistake I might have committed, but this is the way I always find out the LCM. Looks lengthy, but is very quick once you get a hang of it.
