Shubham,
They've asked us to find out the greatest common divisor of two numbers which are less than 144 ?
Sol: So we shouldnt consider 144.
Greatest common divisor of two numbers is the largest( greatest ) number among all the divisors. So it should be less than 72 because as 2 is the min. number ( though 1 is there ) - 2 * 72 = 144.
So lets go with 71 - > 142 = 2 * 71
71 = 1 * 71
So the common divisor will be 71.
