What is the sum of all the common factors of 15 and 65?
Six.
Can you describe a number by both the number of its factors and the kinds of its factors?
There are more than just prime and composite, there are 3 other types which you can describe a number by the kind of factors. They are abundant number, deficient number, and perfect number. An abundant number is a number which if its factors were all added up , the sum would be greater than the number itself. A deficient number is a number in which if all its factors were added up the sum would be less than the number itself. A perfect number is in which a numbers factors are added up and the sum will be the same number as the number itself. Example of abundant number: 12 because these are its factors, 1+2+3+4+6 which equals 16 and 16 is greater than 12. Example of a deficient number: 15 because 15's factors are 1+3+5 which equals 9 and 9 is less than 15. Example of a perfect number: 6 because 6's factors are 1+2+3 which equals 6 and 6 is the same as 6
What is the sum of all the common factors of 99 and 33?
To find the common factors of 99 and 33, we first need to find the factors of each number. The factors of 99 are 1, 3, 9, 11, 33, and 99. The factors of 33 are 1, 3, 11, and 33. The common factors are 1, 3, and 11. Adding these common factors together gives us 1 + 3 + 11 = 15. Therefore, the sum of all the common factors of 99 and 33 is 15.
