Method 1:
\List the factors of each number.
\Factors of 115 : 5, 23, 115
\Factors of 207 : 3 , 9, 23, 69 , 207
\Identify the greatest common factor.
\The greatest common factor of 115 and 207 is 23.
\The GCF is 23. So, the numbers are not relatively prime.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
Method 2:
\Write the prime factorization of each number.
\115 = 5 × 23.
\207 = 3 × 3 × 23.
\The GCF is the product of the common prime factors in each number.
\GCF = 23.
\The greatest common factor of 115 and 207 is 23.
\The GCF is 23. So, the numbers are not relatively prime.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The greatest common factor of 115 and 207 is 23.So, the numbers are not relatively prime.
