I'm sorry! First, I combined all the tests into one. Secondly, my mistake was that I did not understand that it was necessary to reduce numbers when dividing integers.
The length of my code is 100 lines. I was surprised when I saw a short solution from other people(as always). A good kata, thanks!

Kata does not work correctly in Kotlin. Example,
a = arrayOf(intArrayOf(1, 2), intArrayOf(2, 9), intArrayOf(3, 18), intArrayOf(4, 24), intArrayOf(6, 48), intArrayOf(1, 2), intArrayOf(1, 3), intArrayOf(1, 4), intArrayOf(1, 3), intArrayOf(5, 3))

Result should be [307, 72]
But in kata [6, 3]

The author, please fix it. Can't complete kata!
