1+1+4+4444+1928+63626 = 70004
Answer:
28
Step-by-step explanation:
We will keep dividing by prime numbers until both are one (we will only consider whole divisions)
```
14 28 | 2
7 14 | 2
7 7 | 7
1 1
Now we <em>m</em><em>u</em><em>l</em><em>t</em><em>i</em><em>p</em><em>l</em><em>y</em> the left collumn, to get the LCM
2 * 2 * 7 = 28
And this was the vertical method, ok?
