i just want to re make sure that the following question is correct.
(1) List all the factors of 16
My answer: 1,2,4,8,16
That is correct. They may not want 1 and 16 to be included, since every integer has 1 and itself as factors.
so i should take away the 1 and 16
A factor of a number N is any number that evenly divides N.
Therefore, the factors of 16 are 1,2,4, 8 and 16.
A proper divisor of a number N is any number that divides N except the number N itself. 1, 3 and 7 are the proper divisors of 21.
Proper divisors are often referred to the aliquot parts of a number.
