Greatest Common Divisor (GCD) of 3, 6 and 63

The Greatest Common Divisor (GCD) of 3, 6 and 63 is the largest positive integer that equally divides all three numbers: 3, 6 and 63. Mathematically, the problem we are solving is:

GCD(3,6,63)

To solve the problem, we will list all the positive integers (divisors) that can be divided into 3, 6 and 63. We will then compare the lists of divisors to find the greatest divisor they have in common.

Divisors of 3:
1 and 3.

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

Divisors of 63:
1, 3, 7, 9, 21, and 63.

When we compare the lists of divisors above, we see that the largest number they have in common is 3. Thus, the Greatest Common Divisor (GCD) of 3, 6 and 63 is:

GCD(3,6,63) = 3
