Remember that if two numbers are relatively prime, they share no common factors beside 1. First, let's examine the factors of both 182 and 195. To do this, simply divide the numbers until you can divide no more!
[tex]182 = 2 \cdot 91 = 2 \cdot 7 \cdot 13[/tex]
[tex]195 = 5 \cdot 39 = 5 \cdot 13 \cdot 3[/tex]
You can see that both numbers have a factor of 13, meaning that they are not relatively prime.
