Greatest Common Factor of 924 and 64
GCF(924, 64) = 4, Greatest common factor of 924 and 64 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 924 and 64. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 924 and 64 by prime factorization method
We will first find the prime factorization of 924 and 64.
Prime Factorization of 924 is 1, 2, 2, 3, 7, 11 and Prime Factorization of 64 is 1, 2, 2, 2, 2, 2, 2.
- Factorize\( (924) = \) \(1\times 2\times 2\times 3\times 7\times 11\)
- Factorize\( (64) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 2\)
Now we need to find any which are common for each number (1, 2, 2) and multiply these numbers together.
\(GCF(924, 64) = 1\times 2\times 2 = 4\).
Greatest Common Factor of 924 and 64 by matching factors method
List of positive integers factors of 924 leaving a remainder zero is 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
List of positive integers factors of 64 leaving a remainder zero is 1, 2, 4, 8, 16, 32, 64
