I have been looking at the sequence of answers for a pattern there.

**New Problem:**

**Find the smallest natural number for which, if you move its last digit to the beginning, you get a number that is 6 times the original. Or prove that no such number can exist.**

**A says) Finally some real mathematics, I have a proof using Banach spaces that no such number can exist!**

**B says)I have the number. It is**

**C says) Hold on B, how can you have the number after A proved it can not exist? You should not go off making spurious claims. A has done it again.**

**D says) A has confused me again.**

**E says) I have the number too but it is larger than B's.**

**Who is right? Can there be at least 2 solutions or no solutions?**

**In mathematics, you don't understand things. You just get used to them.****If it ain't broke, fix it until it is.**

How do you solve that?

'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

'God exists because Mathematics is consistent, and the devil exists because we cannot prove it'

Hi Agnishom;

There are at least two ways, computer and a little algebra. Actually this makes a good Euler project and you should try it by programming first.

**In mathematics, you don't understand things. You just get used to them.****If it ain't broke, fix it until it is.**

**Online**

It would take too much time for my computer to calculate 50 digits of numbers.

How do I start eliminating possibilities?

Hi;

There is a famous article written by an unknown genius called "Commonsense Brute Force and the Computer," that covers this concept.

**In mathematics, you don't understand things. You just get used to them.****If it ain't broke, fix it until it is.**

**Online**

Why does the genius still wish to remain anonymous???

However, will you please explain the pseudocode to the problem?

Hi;

I will see what I can come up with.

But you already know...

You have already solved the problem

Hi;

Yes, but believe it or not Mathematica makes those problems very easy. I hardly had to do any coding at all!
