Greatest Common Factor of 34 and 56
GCF(34, 56) = 2, Greatest common factor of 34 and 56 is 2. 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 34 and 56. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 34 and 56 by prime factorization method
We will first find the prime factorization of 34 and 56.
Prime Factorization of 34 is 1, 2, 17 and Prime Factorization of 56 is 1, 2, 2, 2, 7.
- Factorize\( (34) = \) \(1\times 2\times 17\)
- Factorize\( (56) = \) \(1\times 2\times 2\times 2\times 7\)
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
\(GCF(34, 56) = 1\times 2 = 2\).
Greatest Common Factor of 34 and 56 by matching factors method
List of positive integers factors of 34 leaving a remainder zero is 1, 2, 17, 34
List of positive integers factors of 56 leaving a remainder zero is 1, 2, 4, 7, 8, 14, 28, 56
As you can see, 2 is the greatest and common number that 34 and 56 divides into.
So the greatest common factor 34 and 56 is 2.
\(GCF(34, 56) = 2\).
