Greatest Common Factor of 56 and 356
GCF(56, 356) = 4, Greatest common factor of 56 and 356 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 56 and 356. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 56 and 356 by prime factorization method
We will first find the prime factorization of 56 and 356.
Prime Factorization of 56 is 1, 2, 2, 2, 7 and Prime Factorization of 356 is 1, 2, 2, 89.
- Factorize\( (56) = \) \(1\times 2\times 2\times 2\times 7\)
- Factorize\( (356) = \) \(1\times 2\times 2\times 89\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(56, 356) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 56 and 356 by matching factors method
