Answer 2

Given:

Consider the given condition is

(13, 17) = 1

Find:

(30, 221) = ?

Solution:

Since we have given that (13, 17) = 1

or we can say that the gcd(13, 17) = 1 that is nothing is common between 13 and 17 expect 1

therefore 1 is the common factor between the given numbers.

So in th egiven options no number is common between 30 and 221 as factor so the answer is 1

hence th ecorrect optiion is (A)
