Greatest Common Divisor (GCD) of 60 and 78

The Greatest Common Divisor (GCD) of 60 and 78 is the largest positive integer that divides both 60 and 78. Mathematically, the problem we are solving is:

GCD(60,78)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 60 and 78. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 60:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

Divisors of 78:
1, 2, 3, 6, 13, 26, 39, and 78.

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 60 and 78 is:

GCD(60,78) = 6
