How many were there?

After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb.
Matthew 28:1
When the Sabbath was over, Mary Magdalene, Mary the mother of James, and Salome bought spices so that they might go to anoint Jesus' body.
Mark 16:1
It was Mary Magdalene, Joanna, Mary the mother of James, and the others with them who told this to the apostles.
Luke 24:10

I think there were more than three women. It looks like they have either visited the tomb in groups or as singles, either at different times or at the same time. If they were in groups it is also likely that the writer chose certain women represetatives based on their knowledge.
None of the verses speaks of these three being the only persons to travel to the tomb.
Thank you! I looked it up, but wasn't sure because each book mentioned different people. I knew that all the accounts are true, I just got confused. Thank you for your help! :-D
