What are proper numbers?
You might be thinking of proper factors. Proper factors are just like the set of regular factors, except for 1 and the number itself.
Is 9 prime?
No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. No 9 is not prime. It's factors are 1,3,9. Proper factors: 1,3. Factors are numbers that are multiplied with other numbers to get a product. Proper factors are factors of a number except for itself. Composite numbers are numbers with more than 2 factors and more than 1 proper factor. Prime is the opposite of composite.
What are the proper factors of 40?
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.
What are the proper factors of the numbers from 1 to 100?
The proper factors of a number are all its factors except itself. Sometimes, the number 1 is also excluded. So, the proper factors of 6 are either 1, 2, and 3, or if excluding the number 1, they are 2 and 3. (If your instructor distinguishes between proper factors and proper divisors, then proper factors are all the factors of a number except 1 and itself, while proper divisors are all the factors of a number except itself, but often proper factors is the only term used, so check whether 1 is included in the definition you are using.)The list of factors in the question "What are the factors of the numbers from 1 to 100" (see link below) includes both 1 and the number itself, but if you remove the number itself, and the 1 if it is excluded in the definition of proper factor that you are using, you will have the complete list of proper factors.The prime numbers, which only have themselves and 1 as factors, are in bold in the list of factors on that page. Their proper factors are either the number 1, or if 1 is excluded, they have no proper factors.Short List of Proper Factors:As an example, here are the proper factors (including 1, which is sometimes used and sometimes not) for the first 10 numbers:1: No proper factors2: 13: 14: 1, 25: 16: 1, 2, 37: 18: 1, 2, 49: 1, 310: 1, 2, 5A less unwieldy versionIn practice, it seems unlikely that anyone wants you to continue the above list to 100. (That would be 3 sides of handwritten A4 paper.) Maybe they only wanted to know which numbers appear in the list of proper factors. For example, the proper factors of numbers from 1 to 10 are 1, 2, 3, 4 and 5 (as you can see above).
What are the proper factors for 31?
31 is a prime number so its only factors are 1 and itself.
What is the certain number for the list of proper factors 1234671214212842498498147196294?
6
What is the number of these proper factors 1234671214212842498498147196294?
That is a list of the proper divisors of 588. Most definitions of proper factors do not include the number 1.
Why is the set of factors of a number not the same as the proper factors of that number?
The proper factors of a number do not include one and the number itself.
What are proper factors of a certain number?
"Proper factors" are all of a number's factors except one and the number itself.
What numbers do not include the number itself?
the proper factors are the factors of a number not including the number itself, or 1.
What is the difference between the factors and the proper factors of a number?
The proper factors are the regular factors without one and the number itself.
Does three have proper factors?
No, no prime number has proper factors.
What are the proper factors for the number 1?
One has no proper factors.
Why is the set of factors of a number not the same as the set of proper factors of the number?
The set of factors includes one and the number itself. Proper factors do not include those two.
Why is a set of factors of a number not the same as a set of proper factors of what number?
Proper factors don't include one and the number itself.
Why is the set of factors of a number not the same as the set of proper factors of that number?
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.
What are the proper factors of 64?
The proper factors of 64 are 2, 4, 8, 16 and 32. For proper factors of a number exclude 1 and the number itself from the list of factors.
