My daughter have a homework of inter-math . she was on 6 grade and I dont understand this: Why is the set of factors of a number not the same as the set of proper factors of that number? Explain and give example.

Re: proper factor
The "proper factors" are the factors other than the number itself. Sometimes 1 is also excluded.
Factors of 12: 1,2,3,4,6,12
Proper Factors of 12: 1,2,3,4,6

Sometimes 1 is called the trivial factor.
