### What is the greatest common divisor of 54 and 24?

Thus the divisors of 54 are: 1 , 2 , 3 , 6 , 9 , 18 , 27 , 54.

Similarly, the divisors of 24 are: 1 , 2 , 3 , 4 , 6 , 8 , 12 , 24.

The numbers that these two lists share in common are the common divisors of 54 and 24:

1 , 2 , 3 , 6.

The greatest of these is 6. That is, the greatest common divisor of 54 and 24.

One writes: gcd ( 54 , 24 ) = 6.
