Greatest Common Factor of 76 and 208
GCF(76, 208) = 4, Greatest common factor of 76 and 208 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 76 and 208. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 76 and 208 by prime factorization method
We will first find the prime factorization of 76 and 208.
Prime Factorization of 76 is 1, 2, 2, 19 and Prime Factorization of 208 is 1, 2, 2, 2, 2, 13.
- Factorize\( (76) = \) \(1\times 2\times 2\times 19\)
- Factorize\( (208) = \) \(1\times 2\times 2\times 2\times 2\times 13\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(76, 208) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 76 and 208 by matching factors method
List of positive integers factors of 76 leaving a remainder zero is 1, 2, 4, 19, 38, 76
