Cƛ96-;2↔ƛġ;:₌Π∆Ŀ=

How it works

C       # Convert the string into a list of ordinals
ƛ96-;   # subtract 96 from each (so that a->1 b->2 c->3 ...)
2↔      # Get a list of all pairs (combinations of size 2)
ƛġ;     # Get the GCD of each pair
:₌Π∆Ŀ   # Get the product and the LCM of the GCDs
=       # Check if they are equal
