Greatest Common Factor of 120 and 3360
GCF(120, 3360) = 120, Greatest common factor of 120 and 3360 is 120. 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 3360. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 120 and 3360 by prime factorization method
We will first find the prime factorization of 120 and 3360.
Prime Factorization of 120 is 1, 2, 2, 2, 3, 5 and Prime Factorization of 3360 is 1, 2, 2, 2, 2, 2, 3, 5, 7.
- Factorize\( (120) = \) \(1\times 2\times 2\times 2\times 3\times 5\)
- Factorize\( (3360) = \) \(1\times 2\times 2\times 2\times 2\times 2\times 3\times 5\times 7\)
Now we need to find any which are common for each number (1, 2, 2, 2, 3, 5) and multiply these numbers together.
\(GCF(120, 3360) = 1\times 2\times 2\times 2\times 3\times 5 = 120\).
Greatest Common Factor of 120 and 3360 by matching factors method
