The two factors of 17 are 1 and 17. Because 17 only has one set of factors, or factor pair, it is a prime number. This means it can only be divided by 1 and itself.Know More
A factor is a number that can be multiplied to produce another number. In this example, 17 is a prime number because it can only be divided evenly, or without leaving a remainder, by itself and 1. Some other prime numbers are 2, 3, 5, 7, 11, 13 and 19. Composite numbers, on the other hand, have more than one factor pair or factorization.
Factoring is useful in algebra and more advanced mathematics, such as calculus, when dealing with quadratics, trinomials and polynomial equations.Learn more about Algebra
The factors of 27 are one, three, nine and 27. The factors of a particular number are those numbers that divide evenly into it. One and the number itself are always factors of any given number.Full Answer >
The factors of six are one, two, three and six. Factors are the numbers that can be multiplied together to get the number being factored. Six multiplied by one equals six, and two multiplied by three equals six; no other positive integers multiplied together result in a product of six.Full Answer >
The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72. Factors are the numbers that can be multiplied together to get 72.Full Answer >
The factors of 21 are 1, 3, 7 and 21. A factor is a number that can divide evenly into a given number. Because 21 can be divided by numbers other than itself and 1, it is called a composite number.Full Answer >
