Greatest Common Divisor (GCD) of 2 and 13

The Greatest Common Divisor (GCD) of 2 and 13 is the largest positive integer that divides both 2 and 13. Mathematically, the problem we are solving is:

GCD(2,13)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 2 and 13. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 2:
1 and 2.

Divisors of 13:
1 and 13.

When we compare the lists of divisors above, we see that the largest number they have in common is 1. Thus, the Greatest Common Divisor (GCD) of 2 and 13 is:

GCD(2,13) = 1
