I would like to convert these numbers to their closest fractional equivalent to see if there is any pattern linking them e.g they are all mutiple of some basic fractional number.

The numbers are:

1.9300728018940605
2.6716041047068817
1.6778839380872763
1.727365137695202

Any guidance is much appreciated!

Rationalize?? – Szabolcs Mar 29 '18 at 21:22
It is mentioned in N's documentation. – Kuba Mar 29 '18 at 21:24
@ Szabolcs. Swift and efficient answers like always! Thanks a lot! – Mitochondria List Mar 29 '18 at 21:27
Actually a simultaneous diophantine approximation might be wanted here. That's somewhat beyond what Rationalize can deliver. – Daniel Lichtblau Mar 30 '18 at 16:27
@Daniel, well, the old NumberTheory`Rationalize` had AffineRationalize[] and ProjectiveRationalize[] for that… – J. M.'s missing motivation Apr 01 '18 at 03:43
@J. M. I know, and I miss those at times. – Daniel Lichtblau Apr 02 '18 at 15:51
