## Which is the greatest common factor for 5 and 27?

It is not difficult to see that the ‘Greatest Common Factor’ or ‘Divisor’ for 5 and 27 is 1. The GCF is the largest common positive integer that divides all the numbers (5,27) without a remainder.

## How to calculate the greatest common factor GCF?

Referring to the previous example, if instead the desired value were GCF (268442, 178296, 66888), after having found that GCF (268442, 178296) is 2, the next step would be to calculate GCF (66888, 2). In this particular case, it is clear that the GCF would also be 2, yielding the result of GCF (268442, 178296, 66888) = 2.

## When is the GCF of an integer is 0?

Once the remainder is 0, the GCF is the remainder from the step preceding the zero result. From the example above, it can be seen that GCF (268442, 178296) = 2. If more integers were present, the same process would be performed to find the GCF of the subsequent integer and the GCF of the previous two integers.
