Rajesh has 235 chocolates. He wants to group them in a way such that every group will have equal number of chocolates. What is the possible group size?
5
For groups of equal size, it is necessary that the group size is a factor of 235.
On prime factorizing 235, we get
235=5×47
Clearly, 235 is divisible by 5 and therefore, it is a factor of 235.
Thus, groups of 5 can be made.
