This sequence is not multiplicative, see example.
EXAMPLE
m=20 and n=63 are coprime:
a(20) = A097246(A097246(2*2*5)) = A097246(3*5)=15,
a(63) = A097246(A097246(3*3*7)) = A097246(5*7)=35 and
a(20*63) = A097246(A097246(2*2*3*3*5*7)) = A097246(3*5*5*7) =
3*7*7 = 147 <> a(20)*a(63) = 15*35 = 525: the sequence is not multiplicative.
