There are no common factors between the two terms 13 x and 10 - see explanation below. Explanation: First, we can try factoring the constants in each term: 13 is a prime number and therefore can only be factored to 1 and 13. 10 can be factored as (1 x 10) or (2 x 5). Because there are no common factors other than 1 the constants cannot be factored. And, because there is no x in the second term (10), we cannot factor an x out of the two terms. Therefore this expression cannot be factored.
