What are the factors of 21 28 and 15?
Factors are those numbers which can be evenly divided into a number. The factors of 21 would be 1, 3, 7, 21 The factors of 28 would be 1, 2, 4, 7, 14, 28 The factors of 15 would be 1, 3, 5, 15
What are factors in mathematics?
Any whole number (integer) has factors. Factors are numbers that can be divided into another number. For example the factors of 15 are: 1, 3, 5 and 15 (1 times 15 and 3 times 5)
How many differnet whole numbers are factors of 15?
To find the factors of a number, you first need to split that number into its prime factors. In the case of 15, this produces: 15 = 3x5 The next step is to note that every factor of the number (apart from 1) is the product of any combination of its prime factors. Thus, the factors of 15 are: 1, 3, 5 and 15.
What are two factors for the number 15?
1,3,5 and 15
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
