Half of the divisors of 28 will be less than the square root, half greater. The square root of 28 is between 5 and 6. So all we need to do is test the numbers 1 to 5 to see if any of them are factors.
1 is because 1 is a factor of everything.
2 is because 28 is even.
3 is not.
4 is.
5 is not.
Divide 1, 2 and 4 into 28
The factors of 28 are 1, 2, 4, 7, 14, 28
