Greatest Common Factor of 3060 and 2805 by prime factorization method

We will first find the prime factorization of 3060 and 2805.
Prime Factorization of 3060 is 1, 2, 2, 3, 3, 5, 17 and Prime Factorization of 2805 is 1, 3, 5, 11, 17.

  • Factorize\( (3060) = \) \(1\times 2\times 2\times 3\times 3\times 5\times 17\)
  • Factorize\( (2805) = \) \(1\times 3\times 5\times 11\times 17\)
Now we need to find any which are common for each number (1, 3, 5, 17) and multiply these numbers together.
\(GCF(3060, 2805) = 1\times 3\times 5\times 17 = 255\).

Greatest Common Factor of 3060 and 2805 by matching factors method
