How to find the Greatest Common Factor

GCF example:

The first step is to find all divisors of each number. For instance, let us find the gcf().

In this case we have:

  • The factors of (all the whole numbers that can divide the number without a remainder) are and 1;
  • The factors of are and 1.

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 0 and is 1. The GCF is the largest common positive integer that divides all the numbers () 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
