Both 7 and 11 are prime numbers. Each one has no other factors besides '1' and itself.

So the only factor they have in common is ' 1'.

(Even if you had picked 2 numbers with 100 factors in each one, you asked for the "least"

common factor. Regardless of what the numbers may be, that's always ' 1 '.)
