Greatest Common Factor of 112 and 256
GCF(112, 256) = 16, Greatest common factor of 112 and 256 is 16. 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 112 and 256. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 112 and 256 by prime factorization method
We will first find the prime factorization of 112 and 256.
Prime Factorization of 112 is 1, 2, 2, 2, 2, 7 and Prime Factorization of 256 is 1, 2, 2, 2, 2, 2, 2, 2, 2.
- Factorize\( (112) = \) \(1\times 2\times 2\times 2\times 2\times 7\)
- Factorize\( (256) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\)
Now we need to find any which are common for each number (1, 2, 2, 2, 2) and multiply these numbers together.
\(GCF(112, 256) = 1\times 2\times 2\times 2\times 2 = 16\).
Greatest Common Factor of 112 and 256 by matching factors method
List of positive integers factors of 112 leaving a remainder zero is 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
