Greatest Common Factor of 9 and 131
GCF(9, 131) = 1, Greatest common factor of 9 and 131 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 9 and 131. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 9 and 131 by prime factorization method
We will first find the prime factorization of 9 and 131.
Prime Factorization of 9 is 1, 3, 3 and Prime Factorization of 131 is 1, 131.
- Factorize\( (9) = \) \(1\times 3\times 3\)
- Factorize\( (131) = \) \(1\times 131\)
Now we need to find any which are common for each number (1, 1) and multiply these numbers together.
\(GCF(9, 131) = 1\times 1 = 1\).
Greatest Common Factor of 9 and 131 by matching factors method
List of positive integers factors of 9 leaving a remainder zero is 1, 3, 9
List of positive integers factors of 131 leaving a remainder zero is 1, 131
