whcih of the following groups would be isomorphic?
The only ones that have a chance of being isomorphic are A5 and Z60. But A5 is non-abelian and Z60 is. So there is no isomorphism here.
60Z4 x Z3 x Z5
44D11 x Z2
32Z4 x Z8
The only possible ones are:
Z4xZ3xZ5 and Z60 and A5
We note the first two are abelian and third one is not.
Thus, it remains to show that the first two are or not isomorphic.
Indeed they are because 4,3,5 in Z4xZ3xZ5 are relatively prime.
