Greatest Common Factor of 40 and 325
GCF(40, 325) = 5, Greatest common factor of 40 and 325 is 5. 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 40 and 325. Greatest Common Factor by prime factorization method and Greatest Common Factor by matching factors method.
Greatest Common Factor of 40 and 325 by prime factorization method
We will first find the prime factorization of 40 and 325.
Prime Factorization of 40 is 1, 2, 2, 2, 5 and Prime Factorization of 325 is 1, 5, 5, 13.
- Factorize\( (40) = \) \(1\times 2\times 2\times 2\times 5\)
- Factorize\( (325) = \) \(1\times 5\times 5\times 13\)
Now we need to find any which are common for each number (1, 5) and multiply these numbers together.
\(GCF(40, 325) = 1\times 5 = 5\).
Greatest Common Factor of 40 and 325 by matching factors method
List of positive integers factors of 40 leaving a remainder zero is 1, 2, 4, 5, 8, 10, 20, 40
List of positive integers factors of 325 leaving a remainder zero is 1, 5, 13, 25, 65, 325
As you can see, 5 is the greatest and common number that 40 and 325 divides into.
So the greatest common factor 40 and 325 is 5.
\(GCF(40, 325) = 5\).
