Greatest Common Factor of 960 and 162

GCF(960, 162) = 6, Greatest common factor of 960 and 162 is 6. 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 960 and 162. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.

Greatest Common Factor of 960 and 162 by prime factorization method

We will first find the prime factorization of 960 and 162.
Prime Factorization of 960 is 1, 2, 2, 2, 2, 2, 2, 3, 5 and Prime Factorization of 162 is 1, 2, 3, 3, 3, 3.

  • Factorize\( (960) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 2\times 3\times 5\)
  • Factorize\( (162) = \) \(1\times 2\times 3\times 3\times 3\times 3\)
Now we need to find any which are common for each number (1, 2, 3) and multiply these numbers together.
\(GCF(960, 162) = 1\times 2\times 3 = 6\).

Greatest Common Factor of 960 and 162 by matching factors method
