How to find the Greatest Common Factor
The first step is to find all divisors of each number. For instance, let us find the gcf(55,88).
In this case we have:
- The factors of 55 (all the whole numbers that can divide the number without a remainder) are 1, 5, 11 and 55;
- The factors of 88 are 1, 2, 4, 8, 11, 22, 44 and 88.
The second step is to analyze which are the common divisors. It is not difficult to see that the 'Greatest Common Factor' or 'Divisor' for 55 and 88 is 11. The GCF is the largest common positive integer that divides all the numbers (55,88) without a remainder.
The GCF is also known as:
- Greatest common divisor (gcd);
- Highest common factor (hcf);
- Greatest common measure (gcm), or
- Highest common divisor
