BASH: Each line of multiple text files gets added to one line

I currently have 3 files with floating point data that I wish to have in a single file with the format:

F1      F1     F3          Output

a1      b1     c1          a1 b1 c1
a2      b2     c2          a2 b2 c2
a3      b3     c3          a3 b3 c3
a4      b4     c4          a4 b4 c4
I would greatly appreciate any intuition on how to go about this.

Thank you in advance!

} 3<"$1" 4<"$2" 5<"$3"
save it to then run

bash F1 F2 F3 > OUTPUT
