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.
Continue ReadingA 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.

Full Answer >The factors of 65 are one, five, 13 and 65. These are the only natural numbers that have 65 as a product when multiplied by one or more other numbers.
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 prime factors of 55 are 5 and 11. Prime factorization means finding the prime numbers that can be multiplied together to produce the original number. The other factors of 55 are 1 and 55, but since neither are prime, they are not considered prime factors.
