Question

Show that the following pairs are coprime-161;192

Answer 1

Answer:

Step-by-step explanation:161 = 7 × 23;

192 = 26 × 3;

Calculate the greatest (highest) common factor (divisor), gcf (gcd):

Take all the common prime factors, by the lowest exponents.  

But the two numbers have no common prime factors.

gcf, gcd (161; 192) = 1;  

coprime numbers (relatively prime)
