GCF(960, 195) = 15, Greatest common factor of 960 and 195 is 15. 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 195. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 960 and 195 by prime factorization method
We will first find the prime factorization of 960 and 195.
Prime Factorization of 960 is 1, 2, 2, 2, 2, 2, 2, 3, 5 and Prime Factorization of 195 is 1, 3, 5, 13.
- Factorize\( (960) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 2\times 3\times 5\)
- Factorize\( (195) = \) \(1\times 3\times 5\times 13\)
Now we need to find any which are common for each number (1, 3, 5) and multiply these numbers together.
\(GCF(960, 195) = 1\times 3\times 5 = 15\).
Greatest Common Factor of 960 and 195 by matching factors method
