This is not a geometric series since -18/54 is not the same as -36/12
18 + 36 + 45 + 9 + 9 + 54 + 27 + 72 + 81 = 351
18 & 81, 27 & 72, 36 & 63, 45 & 54 all fit the description.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 36, 54, and 81 is 9
