Proper factors are all the factors of a number except the number itself. To find the factors of a number, start with 1 and list the factor pairs of the number. For example, the factor pairs of 18 are:
1 x 18
2 x 9
3 x 6
The factors of 18 are: 1, 2, 3, 6, 9, 18.
The proper factors are: 1, 2, 3, 6, 9.
Take the list of regular factors and remove one and the number itself.
Once you have the prime factorization, it is much easier to find the factors, the proper factors, the GCF and LCM.

No. Some proper factors are prime.
One has no proper factors.
1 doesn't have proper factors.
No, no prime number has proper factors.
From the list of regular factors, delete one and the number itself.
List the factors of 54 without 1 and 542, 3, 6, 9, 18, 27
Proper factors do not include one and the number itself.
Prime numbers don't have proper factors.
The proper factors of 26 are 2 and 13
Prime numbers don't have proper factors.
