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
Is 385 a prime number?
A prime number has only 2 factors: 1 and itself. 385 has a 5 in the ones place, so 5 is also a factor. Since 5 X 77 = 385, 77 is a factor, too. There might be other factors. 385 is a composite number because it has more factors than 1 and itself.
How do you get the factors of 2?
