Greatest Common Factor of 108 and 164
GCF(108, 164) = 4, Greatest common factor of 108 and 164 is 4. 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 108 and 164. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 108 and 164 by prime factorization method
We will first find the prime factorization of 108 and 164.
Prime Factorization of 108 is 1, 2, 2, 3, 3, 3 and Prime Factorization of 164 is 1, 2, 2, 41.
- Factorize\( (108) = \) \(1\times 2\times 2\times 3\times 3\times 3\)
- Factorize\( (164) = \) \(1\times 2\times 2\times 41\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(108, 164) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 108 and 164 by matching factors method
