Method 1:
\List the factors of each number.
\Factors of 11 : 11
\Factors of 55 : 5, 11
\Identify the greatest common factor.
\The greatest common factor of 11 and 55 is 11.
\The GCF is 11. 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.
\11 = 11.
\55 = 5 × 11.
\The GCF is the product of the common prime factors in each number.
\GCF = 11.
\The greatest common factor of 11 and 55 is 11.
\The GCF is 11. So, the numbers are not relatively prime.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
