Sharing 60 onions
Calvin and Ken bought a bag of 60 onions. They divide all of these onions between them, such that the number of onions that Ken has is a multiple of the number of onions that Calvin has. Given that Calvin has at least 7 onions, what is the maximum number of onions that Ken has?
Details and assumptions
Each of them have a whole number of onions. They do not cut or split up an individual onion.
