Greatest Common Divisor (GCD) of 4, 18 and 54

The Greatest Common Divisor (GCD) of 4, 18 and 54 is the largest positive integer that equally divides all three numbers: 4, 18 and 54. Mathematically, the problem we are solving is:

GCD(4,18,54)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 4, 18 and 54. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 4:
1, 2, and 4.

Divisors of 18:
1, 2, 3, 6, 9, and 18.

Divisors of 54:
1, 2, 3, 6, 9, 18, 27, and 54.

When we compare the lists of divisors above, we see that the largest number they have in common is 2. Thus, the Greatest Common Divisor (GCD) of 4, 18 and 54 is:

GCD(4,18,54) = 2
