What are proper factors?
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.
Do all proper factors have some factors that you can multiply to get another proper factor?
No. Some proper factors are prime.
What are all the proper factors of 220?
The proper factors of 220 are 2,4,5,10,11,20,22,44,55,110
What number between 20 and 30 has a sum of all its proper factors equal to twice the number itself?
There aren't any numbers like that. You might be thinking of 28, which has a sum of all its factors equal to twice itself, making it a perfect number. Proper factors are a different set.
