What Are the Factors of 17?

Factors are whole numbers that divide the given number completely without leaving any remainder.The factors of 17 are 1 and 17.

This shows that 17 is a prime number because it has no factors other than 1 and itself.

How to Calculate the Factors of 17?

We can use different methods like the divisibility test, prime factorization, and the upside-down division method to calculate the factors of 17. In prime factorization, we express 17 as a product of its prime factors.

Factors of 17 by Prime Factorization

Prime factorization is expressing the number as a product of its factors which are prime. We can do the prime factorization of any number by:

Upside-down division method orFactor tree method

Prime factorization by division method:

We know that 1 is a factor of every number, and 17 is not a multiple of any number. So, we factorize 17 as:


By prime factorization method, we get 17 = 1 × 17. Therefore, there are no other prime factors of 17 other than 17 itself.

Factors of 17 in Pairs

Any set of two numbers that pair up to give the product as 17 are its factor pairs.

17 = 1 × 17

Therefore, the pair factors of 17 are (1, 17). 

A number can have negative pair factors as well. This is because of the fact that the product of two negative numbers is positive.Hence, (-1,-17) is also a factor pair of 17.
