Math Riddle Solved 

I thought it was gonna be 9876543210, it even made it into the finals. That woulda been wild.

I was given this problem by my 2nd grade teacher (I'm pushing 40). It took me 6 weeks to solve it, but I needed to learn and have never forgotten any of the rules you used to identify if something is divisible or not. 7 is a bitch.

"how exciting" killed me lol. Great video!

Simply brilliant as always!!

This is like a weird maths sudoku

You've made my day! Please don't quit youtube (if you are intending to)

somehow reminded me of Sudoku

Bro you're so intelligent!!

I must admit, I cheated... Because numberphile already talked about this number before.

To complex to be fit in my brain😅

How is a+b divisible by 2? Did I miss something? 😂

Can we get the full original problem statement

Whole calculating fgh, where are the possibilities 416 etc?

Que Maravilha!… 😀

How exciting

Hi great video, I have a question. You reset at 3:28 bit 147 would work. One is divisible by 1, 14 is divisible by 2 and 147 is divisible by 3. So 1472589630 could work. Otherwise I misunderstood the riddle 😂 maybe cuz of my English 😅 Many greetings from Germany :)

That’s my phone number 😢

Give me just one month, and I'll give you the answer!
