Greatest Common Factor of 96 and 70
GCF(96, 70) = 2, Greatest common factor of 96 and 70 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 96 and 70. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 96 and 70 by prime factorization method
We will first find the prime factorization of 96 and 70.
Prime Factorization of 96 is 1, 2, 2, 2, 2, 2, 3 and Prime Factorization of 70 is 1, 2, 5, 7.
- Factorize\( (96) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 3\)
- Factorize\( (70) = \) \(1\times 2\times 5\times 7\)
Now we need to find any which are common for each number (1, 2) and multiply these numbers together.
\(GCF(96, 70) = 1\times 2 = 2\).
Greatest Common Factor of 96 and 70 by matching factors method
List of positive integers factors of 96 leaving a remainder zero is 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
List of positive integers factors of 70 leaving a remainder zero is 1, 2, 5, 7, 10, 14, 35, 70
