• ### How do you find the greatest common factor of large numbers?

To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together. Bam! The GCF!

### Is factor tree and prime factorization same?

The factor tree method is quite flexible – at each branch you can break the number into any factors until you reach the prime factors. Although the order of the factors may be different because we can start with different pairs of factors, every factor tree of 36 has the same prime factorization.
