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:
101 = 101
8242 = 2, 13, 317
- Identify the common prime factors:
There are no common prime factors between 101 and 8242.
- Since there are no common prime factors, the GCF is:
GCF(101, 8242) = 1
Thus, the Greatest Common Factor of 101 and 8242, using the prime factorization method, is 1.
This means 101 and 8242 are relatively prime (coprime), having no common factors other than 1.
