How is the greatest common divisor of two numbers calculated?
It is the biggest multiple of all numbers in the set. The GCD is most often calculated for two numbers, when it is used to reduce fractions to their lowest terms. When the greatest common divisor of two numbers is 1, the two numbers are said to be coprime or relatively prime. How is the greatest common divisor calculated?
How is the greatest common factor ( GCF ) calculated?
Include the highest number of occurrences of each prime factor that is common to each original number. Multiply these together to get the GCF. You will see that as numbers get larger the prime factorization method may be easier than straight factoring. The prime factorization of 18 is 2 x 3 x 3 = 18.
