Greatest Common Factor of 120 and 2330
GCF(120, 2330) = 10, Greatest common factor of 120 and 2330 is 10. 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 120 and 2330. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 120 and 2330 by prime factorization method
We will first find the prime factorization of 120 and 2330.
Prime Factorization of 120 is 1, 2, 2, 2, 3, 5 and Prime Factorization of 2330 is 1, 2, 5, 233.
- Factorize\( (120) = \) \(1\times 2\times 2\times 2\times 3\times 5\)
- Factorize\( (2330) = \) \(1\times 2\times 5\times 233\)
Now we need to find any which are common for each number (1, 2, 5) and multiply these numbers together.
\(GCF(120, 2330) = 1\times 2\times 5 = 10\).
Greatest Common Factor of 120 and 2330 by matching factors method
List of positive integers factors of 120 leaving a remainder zero is 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
List of positive integers factors of 2330 leaving a remainder zero is 1, 2, 5, 10, 233, 466, 1165, 2330
