GCF(84, 10000) = 4, Greatest common factor of 84 and 10000 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 84 and 10000. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 84 and 10000 by prime factorization method
We will first find the prime factorization of 84 and 10000.
Prime Factorization of 84 is 1, 2, 2, 3, 7 and Prime Factorization of 10000 is 1, 2, 2, 2, 2, 5, 5, 5, 5.
- Factorize\( (84) = \) \(1\times 2\times 2\times 3\times 7\)
- Factorize\( (10000) = \) \(1\times 2\times 2\times 2\times 2\times 5\times 5\times 5\times 5\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(84, 10000) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 84 and 10000 by matching factors method
