Greatest Common Factor of 204 and 306
GCF(204, 306) = 102, Greatest common factor of 204 and 306 is 102. Greatest Common Factor or Greatest Common Divisor of two numbers is the largest integer by which both the numbers can be divided. There are two different methods to calculate Greatest Common Factor of 204 and 306. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 204 and 306 by prime factorization method
We will first find the prime factorization of 204 and 306.
Prime Factorization of 204 is 1, 2, 2, 3, 17 and Prime Factorization of 306 is 1, 2, 3, 3, 17.
- Factorize\( (204) = \) \(1\times 2\times 2\times 3\times 17\)
- Factorize\( (306) = \) \(1\times 2\times 3\times 3\times 17\)
Now we need to find any which are common for each number (1, 2, 3, 17) and multiply these numbers together.
\(GCF(204, 306) = 1\times 2\times 3\times 17 = 102\).
Greatest Common Factor of 204 and 306 by matching factors method
List of positive integers factors of 204 leaving a remainder zero is 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
List of positive integers factors of 306 leaving a remainder zero is 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
