Greatest Common Divisor (GCD) of 6 and 12

The Greatest Common Divisor (GCD) of 6 and 12 is the largest positive integer that divides both 6 and 12. Mathematically, the problem we are solving is:

GCD(6,12)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 6 and 12. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 6:
1, 2, 3, and 6.

Divisors of 12:
1, 2, 3, 4, 6, and 12.

When we compare the lists of divisors above, we see that the largest number they have in common is 6. Thus, the Greatest Common Divisor (GCD) of 6 and 12 is:

GCD(6,12) = 6
