Greatest Common Factor of 240 and 191
GCF(240, 191) = 1, Greatest common factor of 240 and 191 is 1. 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 240 and 191. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 240 and 191 by prime factorization method
We will first find the prime factorization of 240 and 191.
Prime Factorization of 240 is 1, 2, 2, 2, 2, 3, 5 and Prime Factorization of 191 is 1, 191.
- Factorize\( (240) = \) \(1\times 2\times 2\times 2\times 2\times 3\times 5\)
- Factorize\( (191) = \) \(1\times 191\)
Now we need to find any which are common for each number (1, 1) and multiply these numbers together.
\(GCF(240, 191) = 1\times 1 = 1\).
Greatest Common Factor of 240 and 191 by matching factors method
List of positive integers factors of 240 leaving a remainder zero is 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
List of positive integers factors of 191 leaving a remainder zero is 1, 191
