1,30 2,15 3,10 5,6 Common factors are factors that two or more numbers have in common. A single number cannot have common factors. A single number can have factors, prime factors, and proper factors. The factors of 30 are listed above. The prime factors of 30 are 2, 3, and 5.
Factors are the numbers that evenly divide into a given number.Proper factors are all the factors of the number except the number itself. Some definitions do not allow the number 1, either. If you distinguish between proper factors and proper divisors, proper factors do not include 1, but proper divisors do.Examples:All factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.Proper factors of 54 are 2, 3, 6, 9, 18, and 27.Proper divisors of 54 are 1, 2, 3, 6, 9, 18, and 27.All factors of 9 are 1, 3, and 9.Proper factors of 9 are only 3.Proper divisors of 9 are 1 and 3.All factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.Proper factors of 30 are 2, 3, 5, 6, 10, and 15.Proper divisors of 30 are 1, 2, 3, 5, 6, 10, and 15.All factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.Proper factors of 100 are 2, 4, 5, 10, 20, 25, and 50.Proper divisors of 100 are 1, 2, 4, 5, 10, 20, 25, and 50.All factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.Proper factors of 120 are 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, and 60.Proper divisors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, and 60.

2, 3, 5, 6, 10, 15
1, 2, 3, 5, 6, 10 and 15. Some people do not consider 1 to be a proper factor.
No. Some proper factors are prime.
2, 3, 5, 6, 9, 10, 15, 18, 30, 45
No, no prime number has proper factors.
