Greatest Common Factor of 240 and 3290 by prime factorization method

We will first find the prime factorization of 240 and 3290.
Prime Factorization of 240 is 1, 2, 2, 2, 2, 3, 5 and Prime Factorization of 3290 is 1, 2, 5, 7, 47.

  • Factorize\( (240) = \) \(1\times 2\times 2\times 2\times 2\times 3\times 5\)
  • Factorize\( (3290) = \) \(1\times 2\times 5\times 7\times 47\)
Now we need to find any which are common for each number (1, 2, 5) and multiply these numbers together.
\(GCF(240, 3290) = 1\times 2\times 5 = 10\).
