Hi,
Sorry, I don't use the ladder method, but I can show you how to find the <span>least common multiple of 2 numbers using a different method:
Let's say we are finding the least common multiple of 3 and 9:
3: 3, 6, 9, 12, 15, 18
--
-------------------------------
9: 9, 18, 27, 36, 45, 54
--
All I did was list multiples of both the numbers till I found one that was common (however, in the example above, I listed a few extra)
Hope this helped
:)

Answer:
Step-by-step explanation:
We start with the equation:
We want to find the value of:
We can start with our previous equation and multiply both sides by a:
Now we can rewrite our initial expression as:
Replacing that in the right side, we get:
Now again, let's multiply both sides by a
So we can conclude that:
