Nine proper factors: 1 2 4 5 10 20 25 50 100.
No, no prime number has proper factors.
24 has eight factors, which means it has six proper factors.
The set of factors includes one and the number itself. Proper factors do not include those two.
97 is prime. Prime numbers don't have proper factors.
1,2,4,5,10
The factors pairs of 20 are 1x20, 2x10, and 4x5 so 20 has 6 factors and 5 proper factors.
The proper factors of 100 are 2, 4, 5, 10, 20, 25 and 50.
1, 2, 4, 5, 8, 10, 20, 40. Technically, that's correct, but proper factors are the factors of a number EXCEPT the number itself. So, the PROPER FACTORS of 40 would be 1, 2, 4, 5, 8, 10, and 20.

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.
