That is not a "question", it is an equation. The

**question**is "what do you want to do with that equation?" - Aug 26th 2012, 07:37 PMMaxJasperRe: Looking for help
Two values:

**abc ={81, 891}**Other values up to 1000,000

**abcdef= {81, 891, 8181, 8991, 81081, 89991, 810081, 818181, 891891, 899991}**

You can solve:

1998*(c+10b+100a)=8991*(a+10b+100c)

a=(70b+898c)/191 :: 70b+898c=0 mod(191) ==> b=9, c=1, a=8 ==> abc=891
