Prime Factorization Method
There are multiple ways to find the greatest common factor of given integers. One of these involves computing the prime factorizations of each integer, determining which factors they have in common, and multiplying these factors to find the GCD.
- Find the prime factorization of each number:
33 = 3, 11
11 = 11
- Identify the common prime factors between 33 and 11: 11
- To find GCF multiply the common prime factors: GCF(33, 11) = 11
