All numbers have factors. Some factors are prime numbers. These are known as prime factors. The set of prime factors is a subset of the set of factors for any given number.
Depending on your definition of proper factors, the set of proper factor factors either doesn't include 1 and/or the number itself for a given number.
The factors of 7 are 1 and 7. For them to be common, they need to be compared to another set of factors.The factors of 7 are 1 and 7. For them to be common, they need to be compared to another set of factors.
Proper factors of a number do not include 1 or the number itself. For example, all of the factors of 6 are 1, 2, 3, and 6, but the proper factors of 6 are 2 and 3.
The factors of 12 are 1,2,3,4,6 and 12. For them to be common, they need to be compared to another set of factors.

The set of factors of 18 are {1,2,3,6,9,18} .
The set of proper factors doesn't include 1 and the number itself.
The set of factors of 72 contains the set of factors of 36.
The set of proper factors does not include 1 and the number itself.
The set of factors includes one and the number itself. Proper factors do not include those two.
By comparing its set of factors to another set of factors.
Proper factors don't include one and the number itself.
All non-zero numbers have factors. Some factors are prime, some are composite. The set of prime factors is a subset of the set of total factors.
