n is a positive integer base from 2 to 36 inclusively.
Each of α and β is a
nonzero digit of base n from 1 to n-1 inclusively.
Determine all possible triplets (α, β, n) such that:
(α*β)base n
----------- is a positive integer.
(α.β)base n
### For example, in base ten corresponding to (α, β) = (4, 5), we observe that:
(4*5)/(4.5) = 40/9, which is NOT a positive integer.
(In reply to
computer solution by Charlie)
I compared my list of 77 with Charlie's list of 74.
These are the extra 3 solutions I had:
α β base
1 A 15
A F 21
1 K 30
or, in decimal
1 10 15
A 15 21
1 20 30
I can't figure out why the different results.
